June 2015 N2 - We summarize past and current surveys for WRs among the Local Group galaxies, empha- sizing both the why and how. Such studies are invaluable for helping us learn about massive star evolution, and for providing sensitive tests of the stellar evolution models. But for such surveys to be useful, the completeness limits must be well understood. We illustrate that point by following the “evolution” of the observed WC/WN ratio in nearby galaxies. We end by examining our new survey for WR stars in the Magellanic Clouds, which has revealed a new type of WN star, never before seen.

T1 - Finding Wolf-Rayet Stars in the Milky Way BT - Inputs to Star Formation and Stellar Evolution JF - Wolf-Rayet Stars : Proceedings of an International Workshop held in Potsdam, Germany, 1.–5. June 2015 N2 - The total population of Wolf-Rayet (WR) stars in the Galaxy is predicted by models to be as many as ~6000 stars, and yet the number of catalogued WR stars as a result of optical surveys was far lower than this (~200) at the turn of this century. When beginning our WR searches using infrared techniques it was not clear whether WR number predictions were too optimistic or whether there was more hidden behind interstellar and circumstellar extinction. During the last decade we pioneered a technique of exploiting the near- and mid-infrared continuum colours for individual point sources provided by large-format surveys of the Galaxy, including 2MASS and Spitzer/GLIMPSE, to pierce through the dust and reveal newly discovered WR stars throughout the Galactic Plane. The key item to the colour discrimination is via the characteristic infrared spectral index produced by the strong winds of the WR stars, combined with dust extinction, which place WR stars in a relatively depopulated area of infrared colour-colour diagrams. The use of the Spitzer/GLIMPSE 8µm and, more recently, WISE 22µm fluxes together with cross-referencing with X-ray measurements in selected Galactic regions have enabled improved candidate lists that increased our confirmation success rate, achieved via follow-up infrared and optical spectroscopy. To date a total of 102 new WR stars have been found with many more candidates still available for follow-up. This constitutes an addition of ~16% to the current inventory of 642 Galactic WR stars. In this talk we review our methods and provide some new results and a preliminary review of their stellar and interstellar medium environments. We provide a roadmap for the future of this search, including statistical modeling, and what we can add to star formation and high mass star evolution studies.

T1 - Massive Wolf-Rayet stars on the verge to explode BT - the properties of the WO stars JF - Wolf-Rayet Stars : Proceedings of an International Workshop held in Potsdam, Germany, 1.–5. June 2015 N2 - The enigmatic oxygen-sequence Wolf-Rayet stars represent a rare stage in the evolution of massive stars. Their properties can provide unique constraints on the pre-supernova evolution of massive stars. This work presents the results of a quantitative spectroscopic analysis of the known single WO stars, with the aim to obtain the key stellar parameters and deduce their evolutionary state.X-Shooter spectra of the WO stars are modeled using the line-blanketed non-local thermal equilibrium atmosphere code cmfgen. The obtained stellar parameters show that the WO stars are very hot, with temperatures ranging from 150 kK to 210 kK. Their chemical composition is dominated by carbon (>50%), while the helium mass fraction is very low (down to 14%). Oxygen mass fractions reach as high as 25%. These properties can be reproduced with dedicated evolutionary models for helium stars, which show that the stars are post core-helium burning and very close to their eventual supernova explosion. The helium-star masses indicate initial masses or approximately 40 - 60M⊙.Thus, WO stars represent the final evolutionary stage of stars with estimated initial masses of 40 - 60M⊙. They are post core-helium burning and may explode as type Ic supernovae within a few thousand years.

June 2015 N2 - Professional and amateur astronomers around the world contributed to a 4-month long campaign in 2013, mainly in spectroscopy but also in photometry, interferometry and polarimetry, to observe the first 3 Wolf-Rayet stars discovered: WR 134 (WN6b), WR 135 (WC8) and WR 137 (WC7pd+O9). Each of these stars are interesting in their own way, showing a variety of stellar wind structures. The spectroscopic data from this campaign were reduced and analyzed for WR 134 in order to better understand its behavior and long-term periodicity in the context of CIRs in the wind. We will be presenting the results of these spectroscopic data, which include the confirmation of the CIR variability and a time-coherency of ∼ 40 days (half-life of ∼ 20 days).

T1 - The Discovery and Physical Parameterization of a New Type of Wolf-Rayet Star JF - Wolf-Rayet Stars : Proceedings of an International Workshop held in Potsdam, Germany, 1.–5. June 2015 N2 - As part of our ongoing Wolf-Rayet (WR) Magellanic Cloud survey, we have discovered 13 new WRs. However, the most exciting outcome of our survey is not the number of new WRs, but their unique characteristics. Eight of our discoveries appear to belong to an entirely new class of WRs. While one might naively classify these stars as WN3+O3V binaries, such a pairing is unlikely. Preliminary CMFGN modeling suggests physical parameters similar to early-type WNs in the Large Magellanic Cloud except with mass-loss rates three to five times lower and slightly higher temperatures. The evolution status of these stars remains an open question.

T1 - Finding new Wolf-Rayet stars in the Magellanic Clouds JF - Wolf-Rayet Stars : Proceedings of an International Workshop held in Potsdam, Germany, 1.–5. June 2015 N2 - Obtaining a complete census of massive, evolved stars in a galaxy would be a key ingredient for testing stellar evolution models. However, as the evolution of stars is also strongly dependent on their metallicity, it is inevitable to have this kind of data for a variety of galaxies with different metallicities. Between 2009 and 2011, we conducted the Magellanic Clouds Massive Stars and Feedback Survey (MSCF); a spatially complete, multi-epoch, broad- and narrow-band optical imaging survey of the Large and Small Magellanic Clouds. With the inclusion of shallow images, we are able to give a complete photometric catalog of stars between B ≈ 18 and B ≈ 19 mag. These observations were augmented with additional photometric data of similar spatial res- olution from UV to IR (e.g. from GALEX, 2MASS and Spitzer) in order to sample a large portion of the spectral energy distribution of the brightest stars (B < 16 mag) in the Magel- lanic Clouds. Using these data, were are able to train a machine learning algorithm that gives us a good estimate of the spectral type of tens of thousands of stars. This method can be applied to the search for Wolf-Rayet-Stars to obtain a sample of candi- dates for follow-up observations. As this approach can, in principle, be adopted for any resolved galaxy as long as sufficient photometric data is available, it can form an effective alternative method to the classical strategies (e.g. He II filter imaging).

T1 - Hydrodynamic and radiative transfer modeling of X-ray emission from colliding WR winds BT - WR 140 & the Galactic center JF - Wolf-Rayet Stars : Proceedings of an International Workshop held in Potsdam, Germany, 1.–5. June 2015 N2 - Colliding Wolf-Rayet (WR) winds produce thermal X-ray emission widely observed by X-ray telescopes. In wide WR+O binaries, such as WR 140, the X-ray flux is tied to the orbital phase, and is a direct probe of the winds’ properties. In the Galactic center, ~30 WRs orbit the super massive black hole (SMBH) within ~10”, leading to a smorgasbord of wind-wind collisions. To model the X-ray emission of WR 140 and the Galactic center, we perform 3D hydrodynamic simulations to trace the complex gaseous flows, and then carry out 3D radiative transfer calculations to compute the variable X-ray spectra. The model WR 140 RXTE light curve matches the data well for all phases except the X-ray minimum associated with periastron, while the model spectra agree with the RXTE hardness ratio and the shape of the Suzaku observations throughout the orbit. The Galactic center model of the Chandra flux and spectral shape match well in the region r ≤ 3”, but the model flux falls off too rapidly beyond this radius.

T1 - The importance of Wolf-Rayet ionization and feedback on super star cluster evolution JF - Wolf-Rayet Stars : Proceedings of an International Workshop held in Potsdam, Germany, 1.–5. June 2015 N2 - The feedback from massive stars is important to super star cluster (SSC) evolution and the timescales on which it occurs. SSCs form embedded in thick material, and eventually, the cluster is cleared out and revealed at optical wavelengths – however, this transition is not well understood. We are investigating this critical SSC evolutionary transition with a multi-wavelength observational campaign. Although previously thought to appear after the cluster has fully removed embedding natal material, we have found that SSCs may host large populations of Wolf-Rayet stars. These evolved stars provide ionization and mechanical feedback that we hypothesize is the tipping point in the combined feedback processes that drive a SSC to emerge. Utilizing optical spectra obtained with the 4m Mayall Telescope at Kitt Peak National Observatory and the 6.5m MMT, we have compiled a sample of embedded SSCs that are likely undergoing this short-lived evolutionary phase and in which we confirm the presence of Wolf-Rayet stars. Early results suggest that WRs may accelerate the cluster emergence.

Brightness of the star changes together with its spectral class, which varies from WN11 to WN8. Using CMFGEN code we estimated parameters of stellar atmosphere and found that during last ten years bolometric luminosity of the star changed synchronously with stellar magnitude.

T1 - Wolf-Rayet stars as supernova progenitors JF - Wolf-Rayet Stars : Proceedings of an International Workshop held in Potsdam, Germany, 1.–5. June 2015 N2 - In this review, I discuss the suitability of massive star progenitors, evolved in isolation or in interacting binaries, for the production of observed supernovae (SNe) IIb, Ib, Ic. These SN types can be explained through variations in composition. The critical need of non-thermal effects to produce He I lines favours low-mass He-rich ejecta (in which ^56 Ni can be more easily mixed with He) for the production of SNe IIb/Ib, which thus may arise preferentially from moderate-mass donors in interacting binaries. SNe Ic may instead arise from higher mass progenitors, He-poor or not, because their larger CO cores prevent efficient non-thermal excitation of He i lines. However, current single star evolution models tend to produce Wolf-Rayet (WR) stars at death that have a final mass of > 10 M⊙. Single WR star explosion models produce ejecta that are too massive to match the observed light curve widths and rise times of SNe IIb/Ib/Ic, unless their kinetic energy is systematically and far greater than the canonical value of 10^56 erg. Future work is needed to evaluate the energy/mass degeneracy in light curve properties. Alternatively, a greater mass loss during the WR phase, perhaps in the form of eruptions, as evidenced in SNe Ibn, may reduce the final WR mass. If viable, such explosions would nonetheless favour a SN Ic, not a Ib.

T1 - Post-common-envelope Wolf-Rayet central stars of planetary nebulae JF - Wolf-Rayet Stars : Proceedings of an International Workshop held in Potsdam, Germany, 1.–5. June 2015 N2 - Nearly 50 post-common-envelope (post-CE) close binary central stars of planetary nebulae (CSPNe) are now known. Most contain either main sequence or white dwarf (WD) companions that orbit the WD primary in around 0.1–1.0 days. Only PN G222.8–04.2 and NGC 5189 have post-CE CSPNe with a Wolf-Rayet star primary (denoted [WR]), the low-mass analogues of massive Wolf-Rayet stars. It is not well understood how H-deficient [WR] CSPNe form, even though they are relatively common, appearing in over 100 PNe. The discovery and characterisation of post-CE [WR] CSPNe is essential to determine whether proposed binary formation scenarios are feasible to explain this enigmatic class of stars. The existence of post-CE [WR] binaries alone suggests binary mergers are not necessarily a pathway to form [WR] stars. Here we give an overview of the initial results of a radial velocity monitoring programme of [WR] CSPNe to search for new binaries. We discuss the motivation for the survey and the associated strong selection effects. The mass functions determined for PN G222.8–04.2 and NGC 5189, together with literature photometric variability data of other [WR] CSPNe, suggest that of the post-CE [WR] CSPNe yet to be found, most will have WD or subdwarf O/B-type companions in wider orbits than typical post-CE CSPNe (several days or months c.f. less than a day).

T1 - The end stages of massive star evolution BT - WR stars as SN Ibc progenitors JF - Wolf-Rayet Stars : Proceedings of an International Workshop held in Potsdam, Germany, 1.–5. June 2015 N2 - The morphological appearance of massive stars across their post-Main Sequence evolution and before the SN event is very uncertain, both from a theoretical and observational perspective. We recently developed coupled stellar evolution and atmospheric modeling of stars done with the Geneva and CMFGEN codes, for initial masses between 9 and 120 M⊙. We are able to predict the observables such as the high-resolution spectrum and broadband photometry. Here I discuss how the spectrum of a massive star changes across its evolution and before death, with focus on the WR stage. Our models indicate that single stars with initial masses larger than 30 M⊙ end their lives as WR stars. Depending on rotation, the spectrum of the star can either be that of a WN or WO subtype at the pre-SN stage. Our models allow, for the first time, direct comparison between predictions from stellar evolution models and observations of SN progenitors.

T1 - Physics of massive stars relevant for the modeling of Wolf-Rayet populations JF - Wolf-Rayet Stars : Proceedings of an International Workshop held in Potsdam, Germany, 1.–5. June 2015 N2 - Key physical ingredients governing the evolution of massive stars are mass losses, convection and mixing in radiative zones. These effects are important both in the frame of single and close binary evolution. The present paper addresses two points: 1) the differences between two families of rotating models, i.e. the family of models computed with and without an efficient transport of angular momentum in radiative zones; 2) The impact of the mass losses in single and in close binary models.

T1 - The True origin of Wolf-Rayet stars JF - Wolf-Rayet Stars : Proceedings of an International Workshop held in Potsdam, Germany, 1.–5. June 2015 N2 - The Wolf-Rayet (WR) phenomenon is widespread in astronomy. It involves classical WRs, very massive stars (VMS), WR central stars of planetary nebula CSPN [WRs], and supernovae (SNe). But what is the root cause for a certain type of object to turn into an emission-line star? In this contribution, I discuss the basic aspects of radiation-driven winds that might reveal the ultimate difference between WR stars and canonical O-type stars. I discuss the aspects of (i) self-enrichment via CNO elements, (ii) high effective temperatures (Tₑff), (iii) an increase in the helium abundance (Y ), and finally (iv) the Eddington factor Γₑ. Over the last couple of years, we have made a breakthrough in our understanding of Γₑ -dependent mass loss, which will have far-reaching consequences for the evolution and fate of the most massive stars in the Universe. Finally, I discuss the prospects for studies of the WR phenomenon in the highest redshift Lyα and He ii emitting galaxies.

June 2015 N2 - We present results of full 3D hydrodynamical and radiative transfer simulations of the colliding stellar winds in the massive binary system η Carinae. We accomplish this by applying the SimpleX algorithm for 3D radiative transfer on an unstructured Voronoi-Delaunay grid to recent 3D smoothed particle hydrodynamics (SPH) simulations of the binary colliding winds. We use SimpleX to obtain detailed ionization fractions of hydrogen and helium, in 3D, at the resolution of the original SPH simulations. We investigate several computational domain sizes and Luminous Blue Variable primary star mass-loss rates. We furthermore present new methods of visualizing and interacting with output from complex 3D numerical simulations, including 3D interactive graphics and 3D printing. While we initially focus on η Car, the methods employed can be applied to numerous other colliding wind (WR 140, WR 137, WR 19) and dusty `pinwheel' (WR 104, WR 98a) binary systems. Coupled with 3D hydrodynamical simulations, SimpleX simulations have the potential to help determine the regions where various observed time-variable emission and absorption lines form in these unique objects.

June 2015 N2 - Wolf-Rayet stars are important sources for the enrichment of the ISM with nuclear processed elements, UV photons and momentum. They are descendants of high-mass stars for which short lifetimes and transition times can hamper the spectral classification of the stars in their different evolutionary phases. The expanded stellar atmospheres of Wolf-Rayet stars can show spectra which seem inconsistent with the anticipated underlying evolution phase, for example in late hydrogen-burning WN stars and Of/WN transition stars. We present a sequence of synthetic spectra of the Potsdam Wolf-Rayet models based on the latest Geneva stellar evolution models. This will visualize the changes in stellar spectra over a full stellar lifetime. Direct comparison with observed stellar spectra, as well as the evolution of diagnostic line ratios will improve the connection of spectral classification and evolution phase.

Located in the Small Magellanic Cloud, it is an ideal system for studying the massive star structure and evolutionary processes in low-metallicity environments. Intensely observed over the past few decades, HD5980 is a treasure trove of information on stellar wind structure, on wind-wind collisions and on the formation of wind-blown circumstellar structures. In addition, its characteristics suggest that the eclipsing WR+LBV stars of the system are the product of quasihomogeneous chemical evolution, thus making them candidate pair production supernovae or GRB progenitors.

JF - Wolf-Rayet Stars : Proceedings of an International Workshop held in Potsdam, Germany, 1.–5. June 2015 N2 - The evolution of massive stars is strongly influenced by their initial chemical composition. We have computed rapidly-rotating massive star models with low metallicity (∼1/50 Z⊙) that evolve chemically homogeneously and have optically-thin winds during the main sequence evolution. These luminous and hot stars are predicted to emit intense mid- and far-UV radiation, but without the broad emission lines that characterize WR stars with optically-thick winds. We show that such Transparent Wind UV-Intense (TWUIN) stars may be responsible for the high number of He ii ionizing photons observed in metal-poor dwarf galaxies, such as IZw 18. We find that these TWUIN stars are possible long-duration gamma-ray burst progenitors.

Die Serie war der Höhepunkt von Tolkatchevs intensiver Auseinandersetzung mit den Erfahrungen, die er als Soldat der Roten Armee, während der Befreiung der Konzentrationslager Majdanek und Auschwitz gemacht hatte. Schockiert von dem dort Gesehenen, zeigt er Jesus als Lagerinsassen, der eine gestreifte Uniform trägt, die alle nur möglichen Diffamierungszeichen aufweist – den jüdischen gelben Stern, das rote Dreieck politischer Gefangener und die individuelle Gefangenennummer. Die numerische Tätowierung am Unterarm ist auch zu sehen. Die verschiedenen Abschnitte des Lagerlebens werden als die der traditionellen Passion Christi dargestellt. Während der Künstler die verschiedenen Phasen des Leidens Jesu kanonisch portraitiert, basiert sein künstlerisches Schaffen auf den der bekannten Malereien der europäischen Renaissance.

N2 - In 1945, Zinovii Shenderovich Tolkatchev (1903–1977), a Soviet artist of Jewish origin, created a striking series of five images entitled “Jesus in Majdanek”. The series was the culmination of Tolkatchev‘s intensive preoccupation with the experience he, as a Red Army soldier, endured upon taking part in liberation of the concentration camps Majdanek and Auschwitz. Shocked by the actual sights he witnessed, he depicted Jesus as an actual camp inmate, wearing a striped uniform marked by every possible defamation sign – the Jewish yellow star, the red triangle of political prisoners, and the individual prison number, the numerical tattoo on his lower arm can also be seen. The different stages of camp life are portrayed as the traditional Passion of Christ. While showing the actual situations the artist based himself upon the well known European Renaissance paintings canonically depicting Jesus‘ suffering. The article places Tolkatchev‘s series in a broader cultural and visual context by exploring the development of the ‘historical Jesus’ in the 19th century European thought and Russian realist art, and by examining the impact of the German avant-garde. By doing so, a deeper understanding of the universal message Tolkatchev’s works entail is offered.

Nach einem kurzen Blick auf den jüdischen Christus bei Heine analysiert der Beitrag Stefan Zweigs im Horizont des Ersten Weltkriegs und zionistischer Debatten entstandenes, 1917 publiziertes Drama „Jeremias“. Die für die Konzeption des Stückes zentrale Überblendung der Prophetenfigur Jeremias mit Christus treibt, so die These, die problematische Logik einer Opferstellvertretung hervor, die mit der Vorstellung einer durch (Opfer-)Blut konstituierten Gemeinschaft die Frage nach der Schuld (Christusmord) auf Andere verschiebt. Demgegenüber entwirft das Stück in Motiven der einbrechenden ‚Schrecknis‘, der Fremdheit im Eigenen, des Exils und der Weltwanderschaft einen anderen Kosmopolitismus. N2 - Already in the enlightenment’s interest in Jesus’ Jewishness there is a tendency to take it as point of departure for universalizing ideas of mediation between Judaism and Christianity. However, there are also – mostly from a Jewish perspective – objections against such universalism, which denies crucial differences and neglects the violent history of exclusion and persecution. After a short glimpse at the figure of the Jewish Jesus in Heine, the paper analyzes Stefan Zweig’s drama “Jeremiah”, which was written under the impact of the First World War as well as under Zionist debates of the time and published 1917. By interleaving the figure of the prophet Jeremiah with that of Christ, which is central for the conception of the play, it reveals the problematic logic of a vicarious sacrifice which with the idea of a community established by (sacrificial) blood displaces the question of guilt (murder of Christ) onto others. Contrary to this logic, the play reflects on an alternative cosmopolitanism by evoking motivs of horror, otherness within the self, exile and world-wandering.

Im Versuch, diese Beziehungsgeschichte zu rekonstruieren und zu deuten, rücken Einflussgeber aus dem Umfeld der literarischen Avantgarde Berlins sowie der Lebensreformbewegung in den Blick. In einer Verschränkung von quasireligiöser Renaissance und Aufbruchstimmung hin zum ‚Neuen Menschen‘ war Jesus in diesen Zirkeln um die Jahrhundertwende ein beliebtes Motiv und prägte sich, vermittelt über Freundschaften und Wegmarken, auch in Mühsams Schreiben ein. Neben Kain ist es Jesus, der bei Mühsam zur den fünften Stand revolutionierenden Lichtgestalt wird. In diese Bezugnahme spielen Mühsams konfliktreiches Verhältnis zu seinem Vater und dessen Assimilation an das deutsche Bürgertum mit hinein, das keineswegs gänzlich jene aufgeklärten Werte lebte, auf die es sich nominell berief: Statt Freiheit und Gleichheit prävalierten neue Zwänge, Begrenzungen und Ressentiments, wie Mühsam bemerkte. Über Gustav Landauer fand er nicht nur zum Anarchismus, sondern auch zu einer neuen Sprache für die verschüttete Tradition und prägte hierüber seiner Jesusfigur sein Verständnis eines rebellischen Judentums ein, das Mühsam selbst als Revolutionär verkörperte. N2 - In his writings, the German-Jewish poet and anarchist Erich Mühsam (1878−1934) put special emphasis on Jesus. His perception was influenced by members of Berlin’s literary vanguard and the „Lebensreform”-movement. In Mühsams poetry the biblical Cain and Jesus appear as rebellious characters fighting for the rights of declassed people. Mühsams reference to Jesus seems highly autobiographical, as his conflicts with his bourgeois father dominate his poetry and perspective. For the anarchist, Jewish assimilation and with it the Enlightenment seemed incomplete: Instead of freedom and equality new boundaries, new constraints and resentments determined his social reality. In Gustav Landauer’s writings Mühsam found evidence for his anarchical core belief and even more a renewed focus on Judaism. Part of this highly subjective perception was Jesus: a Jewish rebel just like Mühsam.

Folglich vereint der jüdische Knabe Agathon, die Hauptgestalt des zweiten Romanteils, Züge sowohl des jüdischen Messias als auch des christlichen Heilands. Die hohe Anzahl von Anspielungen auf die Figur Jesu und die ästhetische Funktionalisierung christologischer Motive im Roman ist in den Kontext jener „Heimholung Jesu in das Judentum“ einzubetten, die ab dem 19. Jahrhundert mit der Wissenschaft des Judentums einsetzte. Der vorliegende Beitrag wird – vor dem Hintergrund zeitgenössischer Jesus-Deutungen – sowohl auf die Spuren Jesu in der Charakterisierung Agathons als auch auf die Aneignung christologischer Motive vor allem im 2. Romanteil eingehen. Dabei soll insbesondere auf Lou von Salomés Aufsatz „Jesus der Jude“ (1896) als mögliche Quelle verwiesen werden. N2 - Jakob Wassermann’s novel “Die Juden von Zirndorf ” (“The Jews of Zirndorf ”, 1897), an incisive portrait of German-Jewish life, is grounded on different messianic concepts, which can only partly be ascribed to the Jewish tradition as such. The Jewish boy Agathon, who is the main protagonist in the second part of the book, shows traits of both the Jewish Messiah and the Christian Saviour combined. Several references to the figure of Jesus and the aesthetic functionalisation of Christological motifs can be found in the novel. These references have to be read within the context of the “bringing Jesus back home to Judaism”-movement, which emerged the rise of the Wissenschaft des Judentums in the nineteenth century. The present article will – against the background of contemporary interpretations of Jesus – highlight Jesus’ features present in the characterisation of Agathon and investigate the appropriation of Christological motifs especially in the second part of the novel. The role of Lou von Salomé’s Essay “Jesus der Jude” (“Jesus, the Jew”, 1896) as a possible source of Wassermann’s novel will be given special emphasis.

Jüdische Theologen wie Joseph Eschelbacher entwarfen ein Judentum, das, anders als von Harnack dargestellt, bereits jene moderne Gestalt einer Religion erfüllt, die Harnack für das Christentum erst zu erreichen versuchte. Einsteins „vom Dogma abweichende[r] Standpunkt“, der ihm vor Gericht von einem katholischen Geistlichen als Standpunkt eines dissidenten Juden vorgeworfen wurde, hätte durchaus als Beitrag eines jüdischen Literaten zur Apologie des Judentums gelten können, wenn Einstein nicht selbst seine Glaubensbrüder im Verbund mit der von ihm abgelehnten bürgerlichen Ideologie des kapitalistischen Marktes gesehen hätte. N2 - Carl Einstein‘s drama “The bad news” (1921), for which he was put on trial for blasphemy, follows with its critical stance against the Christian doctrine of the crucifixion and resurrection the trend, led by Jewish theologians of that time, of examining Adolf Harnack‘s modernization project of Christianity. Jewish theologians such as Joseph Eschelbacher devised a Judaism that, unlike Harnack‘s judgment, already fulfilled this modern gestalt of a religion that Harnack intended to find for Christianity. Einstein‘s “deviation from the dogma”, for which he was accused of being a dissident Jew by a Catholic priest in court, could easily be considered another contribution to Judaism‘s apologia by a Jewish literary agent. Yet, he remains an outsider, since, according to Einstein himself, even his fellow religious brother became affiliated with capitalism’ bourgeois ideology – an ideology he rejected deeply.
