Thermal or Non-thermal? Diffuse emission in the infall region of stacked galaxy groups
E. Bulbul, X. Zhang, Z. Ding +16
The faint infall regions surrounding the virial radius of galaxy groups remain largely unexplored due to their low X-ray surface brightness. Using the large statistical power of SR…

The SRG/eROSITA all-sky survey: X-ray scaling relations of galaxy groups and clusters in the western Galactic hemisphere
M. E. Ramos-Ceja, L. Fiorino, E. Bulbul +19
The soft X-ray telescope on board the SRG mission, eROSITA, has produced the largest sample to date of galaxy groups and clusters detected via their intracluster and intragroup med…
