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…
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…
Caught in the web: galaxy mergers along cosmic filaments
Carolina Dulcien, Yara L. Jaffe, Jacob P. Crossett +31
Galaxy clusters grow through the accretion of galaxies from groups, filaments, and other clusters. During this process, galaxies may undergo pre-processing in lower-density environ…
New test of the FLRW metric using the distance sum rule
Syksy Rasanen, Krzysztof Bolejko, Alexis Finoguenov
We present a new test of the validity of the Friedmann-Lemaitre-Robertson-Walker (FLRW) metric, based on comparing the distance from redshift 0 to and from to to…
ZENS IV. Similar Morphological Changes associated with Mass- and Environment-Quenching, and the Relative importance of Bulge Growth versus the Fading of Disks
C. M. Carollo, A. Cibinel, S. J. Lilly +6
We use ZENS data at low redshift to study the dependence of the quenched satellite fraction and of the morphological mix of these quenched satellites, on three different environmen…
WFC3 grism confirmation of the distant cluster Cl J1449+0856 at z=2.00: Quiescent and star-forming galaxy populations
Raphael Gobat, Veronica Strazzullo, Emanuele Daddi +7
We present deep Hubble Space Telescope Wide Field Camera 3 slitless spectroscopic observations of the distant cluster Cl J1449+0856. These cover a single pointing with 18 orbits of…
