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…
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…
The eROSITA Final Equatorial-Depth Survey (eFEDS): X-ray stacking analysis of Subaru's optically selected clusters spanning low richness regime
N. T. Nguyen-Dang, N. Ota, N. Okabe +17
This is the second paper in a series exploring the X-ray properties of galaxy clusters optically selected by the Subaru Hyper Suprime-Cam (HSC) survey, using data from the SRG/eROS…
The SRG/eROSITA All-Sky Survey. Detection of shock-heated gas beyond the halo boundary into the accretion region
X. Zhang, E. Bulbul, B. Diemer +16
The hot gas in the outskirts of galaxy cluster-sized halos, extending around and beyond the virial radius into nearby accretion regions, remains among one of the least explored bar…
