We introduce the Hydrangea simulations, a suite of 24 cosmological hydrodynamic zoom-in
simulations of massive galaxy clusters (M 200c= 1014–1015.4 M⊙) with baryon particle …

The first SRG/eROSITA All-Sky Survey (eRASS1) provides the largest intracluster medium-
selected galaxy cluster and group catalog covering the western Galactic hemisphere …

We investigate the roles of major and minor mergers during brightest cluster galaxy (BCG)
assembly using surface brightness profiles, line indices, and fundamental plane relations …

Dwarfs are the largest population of galaxies in number in the nearby Universe. Deep
spectroscopic data are still missing to obtain a better understanding of their formation and …

We present photometric properties of 183 member galaxies in the Abell 426 cluster using
the Sloan Digital Sky Survey (SDSS) imaging and spectroscopic observation. Detailed …

We investigate the mass–velocity dispersion relation (MVDR) in 29 galaxy clusters in the
HIghest X-ray FLUx Galaxy Cluster Sample (HIFLUGCS). We measure the spatially …

We report a photometric study of globular clusters (GCs), ultracompact dwarfs (UCDs), and
dwarf galaxies in the giant merging galaxy cluster Abell 2744 at z= 0.308. Color–magnitude …

Context. The study of substructure is an important step in determining how galaxy clusters
form. Aims. We aim to gain new insights into the controversial dynamical status of MACS …

We computed the luminosity of simulated galaxies of the c-eagle project, a suite of 30 high-
resolution zoom-in simulations of galaxy clusters based on the eagle simulation. The AB …

We present an analysis of the kinematics of a sample of 14 galaxy clusters via velocity
dispersion profiles (VDPs), compiled using cluster parameters defined within the X-Ray …
