Quenched Galaxies in Clusters of Galaxies and Their Outskirts [PDF]
Astrophysical Bulletin, 2020 Based on the SDSS data, the properties of galaxies with quenched star formation (QGs) within the "splashback"-radius of galaxy clusters $R_{\rm sp}$ and beyond it have been studied.

The Hubble constant from galaxy cluster scaling-relation and SNe Ia observations: a consistency test
European Physical Journal C: Particles and Fields, 2023 In this paper, we propose a self-consistent test for a Hubble constant estimate using galaxy cluster and type Ia supernovae (SNe Ia) observations. The approach consists, in a first step, of obtaining the observational value of the galaxy cluster scaling ...

RASS-SDSS Galaxy Cluster Survey. VII. On the Cluster Mass to Light ratio and the Halo Occupation Distribution [PDF]
, 2006 We explore the mass-to-light ratio in galaxy clusters and its relation to the cluster mass. We study the relations among the optical luminosity ($L_{op}$), the cluster mass ($M_{200}$) and the number of cluster galaxies within $r_{200}$ ($N_{gal}$) in a ...

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.

Hubble Frontier Fields: a high-precision strong-lensing analysis of galaxy cluster MACSJ0416.1-2403 using ∼200 multiple images [PDF]
, 2014 We present a high-precision mass model of the galaxy cluster MACSJ0416.1-2403, based on a strong-gravitational-lensing analysis of the recently acquired Hubble Space Telescope Frontier Fields (HFF) imaging data.

The descendents of Lyman Break Galaxies in galaxy clusters: spatial distribution and orbital properties [PDF]
, 2000 We combine semi-analytical methods with a ultra-high resolution simulation of a galaxy cluster (of mass 2.3 10^14h-1Msolar, and 4 10^6 particles within its virial radius) formed in a standard CDM universe to study the spatial distribution and orbital ...

EVIDENCE FOR PARTICLE RE-ACCELERATION IN THE RADIO RELIC IN THE GALAXY CLUSTER PLCKG287.0+32.9 [PDF]
, 2014 Radio relics are diffuse radio sources observed in galaxy clusters, probably produced by shock acceleration during cluster–cluster mergers. Their large size, of the order of 1 Mpc, indicates that the emitting electrons need to be (re)accelerated locally.

Probing the evolution of galaxy clusters using SZ effect and non-thermal emission: First results from A1413 [PDF]
EPJ Web of ConferencesMass is the most fundamental property of galaxy clusters. However, measuring it is still a challenge. Calibrating mass from intracluster medium observables such as the Sunyaev-Zel’dovich (SZ) effect is subject to uncertainty and biases because of the ...

Detection of a Star Forming Galaxy in the Center of a Low-Mass Galaxy Cluster
, 2018 Brightest Cluster Galaxies (BCGs) residing in the centers of galaxy clusters are typically quenched giant ellipticals. A recent study hinted that star-forming galaxies with large disks, so-called superluminous spirals and lenticulars, are the BCGs of a ...
