eROSITA cosmology with galaxy groups: Hot gas budget out to the virial radius
H. Khalil, A. Finoguenov, D. Eckert +4
Non-gravitational processes that expel hot gas beyond the virial regions of groups and clusters of galaxies, known collectively as baryonic feedback, play a key role in reshaping t…
The SRG/eROSITA All-Sky Survey: Early dark energy and Hubble constant from the cluster mass function
J. Strunk, E. Artis, E. Bulbul +23
The evolution of the mass function of massive galaxy clusters is a well-established probe of cosmology. Using the eROSITA X-ray instrument on board the Spectrum Roentgen Gamma (SRG…
Large eROSITA X-ray sources as 2MRS galaxy groups
A. Finoguenov, R. Seppi, D. Eckert +5
We aim to exploit the large area coverage, good sensitivity, and low instrumental background of eROSITA to detect the faint surface brightness emission of galaxy groups from the Tw…
Bound or blown: the fate of hot gas in galaxy groups
R. Seppi, D. Eckert, J. Schaye +14
The impact of AGN feedback on the hot gas content of galaxy groups remains a key uncertainty in galaxy formation and its connection to the large scale structure of the Universe. We…
The impact of strong feedback on galaxy group scaling relations
D. Eckert, R. Seppi, J. Braspenning +16
Feedback from active supermassive black holes alters the distribution of matter in the Universe by injecting energy in the neighbouring hot gaseous medium, which leads to ejection…
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…
