Scaling Properties of Galaxy Groups

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 ...

THE ROLE OF POOR GALAXY CLUSTERS FOR STUDYING SUPERCLUSTER STRUCTURE

Odessa Astronomical Publications, 2008
The distribution of galaxy clusters is analyzed in regions of 6 galaxy superclusters with both measured and estimated redshifts. The positions of ACO and APM galaxy clusters in the regions are compared with the positions of galaxy clusters and groups ...

The Environmental Dependence of the Evolving S0 Fraction [PDF]

, 2010
We reinvestigate the dramatic rise in the S0 fraction, f_S0, within clusters since z ~ 0.5. In particular, we focus on the role of the global galaxy environment on f_S0 by compiling, either from our own observations or the literature, robust line-of ...

How special are brightest group and cluster galaxies? [PDF]

Monthly Notices of the Royal Astronomical Society, 2007
Abstract We use the Sloan Digital Sky Survey (SDSS) to construct a sample of 625 brightest group and cluster galaxies (BCGs) together with control samples of non-BCGs matched in stellar mass, redshift and colour. We investigate how the systematic properties of BCGs depend on stellar mass and on their privileged location near the cluster ...

The Transition Region between Brightest Cluster Galaxies and Intracluster Light in Galaxy Groups and Clusters

The Astrophysical Journal, 2022
Abstract We take advantage of a state-of-art semianalytic model of galaxy formation, and the model presented by Contini & Gu, to investigate the mass distribution of brightest cluster galaxies (BCGs) and intracluster light (ICL) by addressing two points: (1) the region of transition between a BCG-dominated distribution and an ICL ...

On the Origin and Evolution of the Intra-Cluster Light: A Brief Review of the Most Recent Developments

Galaxies, 2021
Not all the light in galaxy groups and clusters comes from stars that are bound to galaxies. A significant fraction of it constitutes the so-called intracluster or diffuse light (ICL), a low surface brightness component of groups/clusters generally found

Dust accretion and destruction in galaxy groups and clusters [PDF]

, 2010
We examine the dust distribution around a sample of 70,000 low redshift galaxy groups and clusters derived from the Sloan Digital Sky Survey. By correlating spectroscopically identified background quasars with the galaxy groups we obtain the relative ...

The radial structure of galaxy groups and clusters [PDF]

, 2003
Simple self-consistent models of galaxy groups and clusters are tested against the results of high-resolution adiabatic gasdynamical simulations. We investigate two models based on the existence of a 'universal' dark matter density profile and two ...

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.
