Galaxy and mass assembly (GAMA): the clustering of galaxy groups [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT We explore the clustering of galaxy groups in the Galaxy and Mass Assembly (GAMA) survey to investigate the dependence of group bias and profile on separation scale and group mass. Due to the inherent uncertainty in estimating the group selection function, and hence the group autocorrelation function, we instead measure the ...

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.

Galaxy structures — groups, clusters and superclusters [PDF]
International Journal of Geometric Methods in Modern Physics, 2014 We provide a brief summary of the history of galaxy structure studies. We also introduce several large-scale redshift surveys and summarize the most commonly used methods to identify the groups and clusters of galaxies. We present several catalogs of galaxy groups. These catalogs can be used to study the galaxy groups in different environments.

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 ...

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 ...

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
