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

Witnessing the growth of the nearest galaxy cluster [PDF]
, 2016 We present results from Suzaku Key Project observations of the Virgo Cluster, the nearest galaxy cluster to us, mapping its X-ray properties along four long `arms' extending beyond the virial radius.

Cosmology with Clusters of Galaxies [PDF]
Particle 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 Stellar Population of Stripped Cluster Spiral NGC 4522: A Local Analog to K+A Galaxies? [PDF]
, 2006 We present observations of the stripped Virgo Cluster spiral NGC 4522, a clear, nearby example of a galaxy currently undergoing ISM-ICM stripping. Utilizing SparsePak integral field spectroscopy on the WIYN 3.5m telescope and GALEX UV photometry, we ...

THE PECULIARITIES IN O-TYPE GALAXY CLUSTERS
Odessa 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.

Mass Distribution in Galaxy Cluster Cores [PDF]
, 2016 Many processes within galaxy clusters, such as those believed to govern the onset of thermally unstable cooling and active galactic nucleus feedback, are dependent upon local dynamical timescales. However, accurate mapping of the mass distribution within

Galaxy subgroups in galaxy clusters [PDF]
Monthly 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.

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 ...
