Chandra centres for COSMOS X-ray galaxy groups: Differences in stellar properties between central dominant and offset brightest group galaxies
Ghassem Gozaliasl, Alexis Finoguenov, Masayuki Tanaka +24
We present the results of a search for galaxy clusters and groups in the square degree of the COSMOS field using all available X-ray observations from the XMM-Newton and Ch…
The Full-Sky Angular Bispectrum in Redshift Space
Enea Di Dio, Ruth Durrer, Roy Maartens +2
We compute the redshift-dependent angular bispectrum of galaxy number counts at tree-level, including nonlinear clustering bias and estimating numerically for the first time the ef…
Brightest group galaxies-II: the relative contribution of BGGs to the total baryon content of groups at z<1.3
Ghassem Gozaliasl, Alexis Finoguenov, Habib G. Khosroshahi +6
We performed a detailed study of the evolution of the star formation rate (SFR) and stellar mass of the brightest group galaxies (BGGs) and their relative contribution to the total…
