A study of the large-scale formation in the environment of A3266: Infalling groups, filaments, and a premerger cold front

J. Dietl, A. Veronica, T. H. Reiprich +7

The paper uses eROSITA X‑ray data to map the outskirts of the galaxy cluster Abell 3266, revealing a hot X‑ray filament linking the cluster to a nearby group and showing how the cl…

Thermal or Non-thermal? Diffuse emission in the infall region of stacked galaxy groups

E. Bulbul, X. Zhang, Z. Ding +16

The authors stack eROSITA X‑ray data for 827 low‑mass galaxy groups to detect faint diffuse emission out to ~2 R200, measuring temperature, density, and metal abundance in the infa…

The SRG/eROSITA All-Sky Survey DR2: Cumulative X-ray catalogues from the first three surveys and multi-wavelength counterparts in the western Galactic hemisphere

M. E. Ramos-Ceja, G. Lamer, M. Salvato +111

The paper presents the second data release of the SRG/eROSITA all‑sky survey, providing catalogues of nearly two million X‑ray sources (point‑like and extended) from the first thre…

X-rays breaking out of pre-explosion ejecta mark a supernova's first light

Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130

Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…

Simulation-Based Inference for Cluster Cosmology with Set-Based Neural Network Architectures

S. Zelmer, E. Bulbul, K. Lehman +18

The unprecedented statistical power of galaxy cluster catalogs from the SRG (Spectrum Roentgen Gamma)/eROSITA All-Sky Survey provides a unique opportunity to place stringent constr…

The three-dimensional shapes of the galaxy cluster intracluster medium in eRASS1

S. Kulkarni, J. S. Sanders, E. Bulbul +2

The three-dimensional shapes of clusters are important for understanding the astrophysics of the clusters and as a probe in cosmological studies. We estimate the most probable thre…
