THE DETERMINATION OF THE MORPHOLOGICAL TYPES OF GALAXY CLUSTERS USING CLUSTER CARTOGRAPHY
Odessa Astronomical Publications, 2016 We discuss the possibility of using the Cluster Cartography set for the determined the morphological types of galaxy clusters. The applied morphological scheme was proposed by Panko (2013).

CLASH-VLT: The Inner Slope of the MACS J1206.2-0847 Dark Matter Density Profile
The Astrophysical Journal, 2023 The inner slope ( γ _DM ) of the dark matter (DM) density profile of cosmological halos carries information about the properties of DM and/or baryonic processes affecting the halo gravitational potential.

The challenging task of determining star formation rates: the case of a massive stellar burst in the brightest cluster galaxy of Phoenix galaxy cluster [PDF]
, 2016 Star formation in galaxies at the center of cooling-flow galaxy clusters is an important phenomenon in the context of formation and evolution of massive galaxies in the Universe. Yet, star formation rates (SFRs) in such systems continue to be elusive. We

The HectoMAP Cluster Survey: Spectroscopically Identified Clusters and their Brightest Cluster Galaxies (BCGs) [PDF]
Astrophysical Journal, 2021 We apply a friends-of-friends (FoF) algorithm to identify galaxy clusters and we use the catalog to explore the evolutionary synergy between brightest cluster galaxies (BCGs) and their host clusters.

The JWST PEARLS View of the El Gordo Galaxy Cluster and of the Structure It Magnifies
The Astrophysical Journal, 2023 The massive galaxy cluster El Gordo ( z = 0.87) imprints multitudes of gravitationally lensed arcs onto James Webb Space Telescope Near-Infrared Camera (NIRCam) images.

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.

How special are brightest group and cluster galaxies? [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 Abstract We use the Sloan Digital Sky Survey (SDSS) to construct a sample of 625 brightest group and cluster galaxies (BCGs) together with control samples of non-BCGs matched in stellar mass, redshift and colour. We investigate how the systematic properties of BCGs depend on stellar mass and on their privileged location near the cluster ...

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 ...

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 )
