Scaling Properties of Galaxy Groups [PDF]
Universe, 2021 Galaxy groups and poor clusters are more common than rich clusters, and host the largest fraction of matter content in the Universe. Hence, their studies are key to understand the gravitational and thermal evolution of the bulk of the cosmic matter ...

Accretion of galaxy groups into galaxy clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 We study the role of group infall in the assembly and dynamics of galaxy clusters in ΛCDM. We select 10 clusters with virial mass M200 ∼1014 M from the cosmological hydrodynamical simulation Illustris and follow their galaxies with stellar mass M⊙ ≥ 1.5 ×

THE PECULIARITIES IN O-TYPE GALAXY CLUSTERS
Odessa Astronomical Publications, 2017 We present the results of analysis of 2D distribution of galaxies in galaxy cluster fields. The Catalogue of Galaxy Clusters and Groups PF (Panko & Flin) was used as input observational data set.

Galaxy Evolution in Groups and Clusters [PDF]
, 2004 In this thesis, we investigate the extent to which galaxy evolution is driven by processes common to the group and cluster environments. A bimodality of galaxy properties such as star formation, strongly dependent upon the local overdensity of galaxies ...

Constraints on the Optical Depth of Galaxy Groups and Clusters [PDF]
The Astrophysical Journal, 2017 Future data from galaxy redshift surveys, combined with high-resolutions maps of the cosmic microwave background, will enable measurements of the pairwise kinematic Sunyaev–Zel'dovich (kSZ) signal with unprecedented statistical significance.

Properties of Fossil Groups of Galaxies
Universe, 2021 We review the formation and evolution of fossil groups and clusters from both the theoretical and the observational points of view. In the optical band, these systems are dominated by the light of the central galaxy.

The Effect of Splashback on Weak Lensing Mass Estimates of Galaxy Clusters and Groups
The Open Journal of Astrophysics, 2023 The splashback radius of a dark matter halo, which corresponds to the first apocenter radius reached by infalling matter and substructures, has been detected around galaxy clusters using a multitude of observational methods, including weak lensing ...
