Galaxy Activity in Merging Binary Galaxy Clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 We present the results of a study of galaxy activity in two merging binary clusters (A168 and A1750) using the Sloan Digital Sky Survey (SDSS) data supplemented with the data in the literature.

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 ...

Cluster–galaxy weak lensing [PDF]
The Astronomy and Astrophysics Review, 2020 AbstractWeak gravitational lensing of background galaxies provides a direct probe of the projected matter distribution in and around galaxy clusters. Here, we present a self-contained pedagogical review of cluster–galaxy weak lensing, covering a range of topics relevant to its cosmological and astrophysical applications.

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 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.

DISCRETE X-RAY SOURCES IN GALAXY CLUSTERS
Odessa Astronomical Publications, 2020 Current studies of extragalactic X-ray sources using data from orbital observatory XMM- Newton are at the front line of X-ray astronomy. Resolution capacity of the observatory instruments enable to detect separate X-ray sources in the close galaxies.

LINEAR SUBSTRUCTURES IN GALAXY CLUSTERS
Odessa Astronomical Publications, 2019 We propose detailed scheme that is describing the morphology of linear substructures in galaxy clusters. Our base morphological scheme di- vides galaxy clusters using numerical criteria according the parameters: concentration to the cluster center, the ...
