The Astrophysical Journal Supplement SeriesWe present the updated galaxy cluster catalog of the second Planck catalog of Sunyaev–Zel’dovich sources (PSZ2) through the compilation of the data for clusters and galaxies with spectroscopically measured redshifts in the literature.

The evolution of galaxy clustering [PDF]
Monthly Notices of the Royal Astronomical Society, 1997 This paper investigates whether nonlinear gravitational instability can account for the clustering of galaxies on large and small scales, and for the evolution of clustering with epoch. No CDM-like spectrum is consistent with the shape of the observed nonlinear spectrum. Unbiased low-density models greatly overpredict the small-scale correlations; high-

, 2013 To demonstrate the feasibility of studying the epoch of massive galaxy cluster formation in a more systematic manner using current and future galaxy surveys, we report the discovery of a large sample of proto-cluster candidates in the 1.62 deg^2 COSMOS ...

Spectroscopic and X-ray Modeling of the Strong Lensing Galaxy Cluster MACS J0138.0-2155
The Open Journal of AstrophysicsWe model the total mass and galactic substructure in the strong lensing galaxy cluster MACS J0138.0-2155 using a combination of Chandra X-ray data, Multi-Unit Spectroscopic Explorer (MUSE) spectroscopy, and Hubble Space Telescope imaging.

X-RAY EMISSION AND ORIENTATION OF SELECTED PF GALAXY CLUSTERS
Odessa Astronomical Publications, 2016 X-ray counterparts for 35 galaxy clusters contained in the PF catalogue of galaxy clusters and groups were found in XMM-Newton archive. 22 ones (all from ACO catalogue) have extended elliptic X-ray haloes appropriate for determination of orientation ...

Bayesian Cluster Finder: Clusters in the CFHTLS Archive Research Survey
, 2011 The detection of galaxy clusters in present and future surveys enables measuring mass-to-light ratios, clustering properties, galaxy cluster abundances and therefore, constraining cosmological parameters.

DARK MATTER AND DARK ENERGY IN THE COMA CLUSTER OF GALAXIES
Odessa Astronomical Publications, 2013 The Coma cluster of galaxies is studied as a giant aggregation of dark matter and baryons embedded in the dark energy background. Key theory relations for the local dark-energy effects are given. On the basis of the theory and current observational data,
