Galaxy subgroups in galaxy clusters [PDF]

Monthly Notices of the Royal Astronomical Society, 2012
Galaxies which fall into clusters as part of the same infall halo can retain correlations due to their shared origin. N-body simulations are used to study properties of such galaxy subgroups within clusters, including their richnesses and prevalence. The

Detection of a Star Forming Galaxy in the Center of a Low-Mass Galaxy Cluster [PDF]

, 2018
Brightest Cluster Galaxies (BCGs) residing in the centers of galaxy clusters are typically quenched giant ellipticals. A recent study hinted that star-forming galaxies with large disks, so-called superluminous spirals and lenticulars, are the BCGs of a subset of galaxy clusters.

Structures in Galaxy Clusters [PDF]

The Astrophysical Journal, 1993
The analysis of the presence of substructures in 16 well-sampled clusters of galaxies suggests a stimulating hypothesis: Clusters could be classified as unimodal or bimodal, on the basis of to the sub-clump distribution in the {\em 3-D} space of ...

Formation of Galaxy Clusters [PDF]

Annual Review of Astronomy and Astrophysics, 2012
In this review, we describe our current understanding of cluster formation: from the general picture of collapse from initial density fluctuations in an expanding Universe to detailed simulations of cluster formation including the effects of galaxy ...

GALAXY DYNAMICS IN CLUSTERS [PDF]

The Astrophysical Journal, 1995
We use high resolution simulations to study the formation and distribution of galaxies within a cluster which forms hierarchically. We follow both dark matter and baryonic gas which is subject to thermal pressure, shocks and radiative cooling.

Detection of anti-correlation of hot and cold baryons in galaxy clusters [PDF]

Nature Communications, 2019
Galaxy clusters contain vast amount of dark matter and baryonic matter. Here the authors show the observational detection of the anti-correlation of gas mass and stellar mass observables in the most massive galaxy clusters, indicating such clusters ...

Interactions of Galaxies in the Galaxy Cluster Environment [PDF]

The Astrophysical Journal, 2009
We study the dependence of galaxy properties on the clustercentric radius and the environment attributed to the nearest neighbor galaxy using the SDSS galaxies associated with the Abell galaxy clusters.

The rotation of Galaxy Clusters [PDF]

Published in Astrofizika, Vol. 58, No. 3, pp. 353-363 (August 2014), 2015
The method for detection of the galaxy cluster rotation based on the study of distribution of member galaxies with velocities lower and higher of the cluster mean velocity over the cluster image is proposed. The search for rotation is made for flat clusters with $a/b>1.8$ and BMI type clusters which are expected to be rotating.

Constructing a Galaxy Cluster Catalog in IllustrisTNG300 Using the Mulguisin Algorithm [PDF]

The Astrophysical Journal
We present a new simulated galaxy cluster catalog based on the IllustrisTNG simulation. We use the Mulguisin (MGS) algorithm to identify galaxy overdensities.
