Starbursting Brightest Cluster Galaxy: a Herschel view of the massive cluster MACS J1931.8-2634 [PDF]
, 2015 We investigate the dust-obscured star formation properties of the massive, X-ray selected galaxy cluster MACS J1931.8{2634 at z=0.352. Using far-infrared (FIR) imaging in the range 100-500 m obtained with the Herschel telescope, we extract 31 sources (2 )

SALT spectroscopic observations of galaxy clusters detected by ACT and a type II quasar hosted by a brightest cluster galaxy [PDF]
Monthly notices of the Royal Astronomical Society, 2014 We present Southern African Large Telescope (SALT) follow-up observations of seven massive clusters detected by the Atacama Cosmology Telescope (ACT) on the celestial equator using the Sunyaev-Zel’dovich (SZ) effect.

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 ...

MORPHOLOGICAL TYPES OF 254 RICH PF GALAXY CLUSTERS
Odessa Astronomical Publications, 2014 We determined the morphological types for 254 rich galaxy clusters from the PF Catalogue of Galaxy Clusters and Groups. The data set contains the PF galaxy clusters, which have no ACO coinciding ones.

Mind the Gap: Tightening the Mass-Richness Relation with Magnitude Gaps [PDF]
, 2013 We investigate the potential to improve optical tracers of cluster mass by exploiting measurements of the magnitude gap, m12, defined as the difference between the r-band absolute magnitude of the two brightest cluster members.

THE ELLIPTICITIES OF GALAXIES IN GALAXY CLUSTERS OF DIFFERENT MORPHOLOGICAL TYPE
Odessa Astronomical Publications, 2014 The distribution of galaxy ellipticities was analyzed for 207 rich PF galaxy clusters found in the Munster Red Sky Survey Galaxy Catalogue. Clusters with BM types from a comparison with the ACO catalogue were also classified on the new scheme.

Intracluster medium cooling, AGN feedback, and brightest cluster galaxy properties of galaxy groups - Five properties where groups differ from clusters [PDF]
, 2014 Aims. We aim to investigate cool-core and non-cool-core properties of galaxy groups through X-ray data and compare them to the AGN radio output to understand the network of intracluster medium (ICM) cooling and feedback by supermassive black holes.
