ON THE DETERMINATION OF GALAXY STRUCTURE ELLIPTICITY

open access: yesOdessa Astronomical Publications, 2007
We discuss factors influencing the determination of the observed shape of galaxy clusters when the covariance ellipse method is involved. The analysis of 377 Abell clusters show that at greater distances from the cluster center the ellipticity is rather ...

Deep Synoptic Array Science: Two Fast Radio Burst Sources in Massive Galaxy Clusters

open access: yesThe Astrophysical Journal Letters, 2023
The hot gas that constitutes the intracluster medium (ICM) has been studied at X-ray and millimeter/submillimeter wavelengths (Sunyaev–Zel’dovich effect) for decades.

Signatures of Galaxy-Cluster Interactions: Spiral Galaxy Rotation Curve Asymmetry, Shape, and Extent [PDF]

open access: yes, 2000
The environmental dependencies of the characteristics of spiral galaxy rotation curves are studied in this work. We use our large, homogeneously collected sample of 510 cluster spiral galaxy rotation curves to test the claim that the shape of a galaxy's ...

Cosmology with Clusters of Galaxies [PDF]

open access: yesParticle Physics and the Universe, 2000
I show that three independent methods utilizing clusters of galaxies - cluster dynamics and mass-to-light ratio, baryon fraction in clusters, and cluster evolution - all indicate the same robust result: the mass-density of the universe is low, Omega ~ 0.2, and the mass approximately traces light on large scales.

THE PECULIARITIES IN O-TYPE GALAXY CLUSTERS

open access: yesOdessa 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.

DISCOVERY OF A GALAXY CLUSTER WITH A VIOLENTLY STARBURSTING CORE AT z = 2.506 [PDF]

open access: yes, 2016
We report the discovery of a remarkable concentration of massive galaxies with extended X-ray emission at zspec = 2.506, which contains 11 massive (M* ≳ 1011 M⊙) galaxies in the central 80 kpc region (11.6σ overdensity).

Galaxy subgroups in galaxy clusters [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2011
Galaxies which fall into clusters as part of the same infall halo can retain correlations due to their shared origin. N-body simulations are used to study properties of such galaxy subgroups within clusters, including their richnesses and prevalence.
