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.

Coordinated Assembly of Brightest Cluster Galaxies [PDF]
The Astrophysical Journal Letters, 2018 Abstract Brightest Cluster Galaxies (BCGs) in massive dark matter halos are shaped by complex merging processes. We present a detailed stellar population analysis in the central region of Abell 3827 at z ∼ 0.1, including five-nucleus galaxies involved in a BCG assembly.

Molecular gas in distant brightest cluster galaxies [PDF]
Astronomy & Astrophysics, 2020 The mechanisms governing the stellar mass assembly and star formation history of brightest cluster galaxies (BCGs) are still being debated. By means of new and archival molecular gas observations we investigate the role of dense megaparsec-scale environments in regulating the fueling of star formation in distant BCGs, through cosmic time.

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.

The Brightest UV-selected Galaxies in Protoclusters at z ∼ 4: Ancestors of Brightest Cluster Galaxies? [PDF]
The Astrophysical Journal, 2019 Abstract We present the results of a survey of the brightest UV-selected galaxies in protoclusters. These proto-brightest cluster galaxy (proto-BCG) candidates are drawn from 179 overdense regions of g-dropout galaxies at z ∼ 4 from the Hyper Suprime-Cam Subaru Strategic Program identified previously as good protocluster candidates.
