Spectroscopy obs. of 20 Planck gal. cluster cand.
We present Gemini and Keck spectroscopic redshifts and velocity dispersions for 20 clusters detected via the Sunyaev-Zel'dovich (SZ) effect by the Planck space mission, with... -
Brightest cluster galaxies bright in 22um (W4BCGs)
Brightest cluster galaxies (BCGs) are believed to have assembled most of their stars early in time and therefore should be passively evolving at low redshifts and appear... -
RELICS: Reionization Lensing Cluster Survey
Large surveys of galaxy clusters with the Hubble Space Telescope (HST) and Spitzer, including the Cluster Lensing And Supernova survey with Hubble and the Frontier Fields, have... -
Evolu. star mass-metallicity relation. II.
We present the stellar mass-[Fe/H] and mass-[Mg/H] relation of quiescent galaxies in two galaxy clusters at z~0.39 and z~0.54. We derive the age, [Fe/H], and [Mg/Fe] for each... -
COBRA Radio source properties
The shape of bent, double-lobed radio sources requires a dense gaseous medium. Bent sources can therefore be used to identify galaxy clusters and characterize their evolutionary... -
Chandra sources in 5 galaxy clusters
We present catalogs and images of optical counterparts to the Chandra-selected X-ray sources found in the fields of the five clusters RX J0152-1357, RX J0849+4452, RDCS... -
ACS Fornax Cluster Survey. I.
The Fornax Cluster is a conspicuous cluster of galaxies in the southern hemisphere and the second largest collection of early-type galaxies within 20Mpc after the Virgo Cluster.... -
Photometry of galaxies in the Coma cluster
We present a set of UBVRIzJHKs photometry for 745 J+H-band-selected objects in a 22.5'x29.2' region centered on the core of the Coma Cluster. This includes 516 galaxies and is... -
Centaurus Cluster catalog
We present a catalog of all galaxies with V<=22.0 and R_iso_>3" within a 0.83deg^2^ region centered on the Centaurus Cluster (Abell 3526) at RA=12h48m, DE=-41{deg}18'.... -
XMM Clusters of galaxies in COSMOS field
We present the results of a search for galaxy clusters in the first 36 XMM-Newton pointings on the Cosmic Evolution Survey (COSMOS) field. We reach a depth for a total cluster... -
The 400d cluster Survey
We present a catalog of galaxy clusters detected in a new ROSAT PSPC survey. The survey is optimized to sample, at high redshifts, the mass range corresponding to T>5keV... -
NEP source catalog
We present a five-band (u g' r' i' z') optical photometry catalog of the sources in the North Ecliptic Pole (NEP) region based on deep observations made with MegaCam at CFHT.... -
WWFI g'-band obs. of bright galaxy clusters
We explore several ways to dissect brightest cluster galaxies (BCGs) and their surrounding intracluster light (ICL) using a surface brightness (SB) cut, a luminosity cut, excess... -
Sunyaev-Zel'dovich galaxy clusters surveyed by ACT
We present a catalog of 4195 optically confirmed Sunyaev-Zel'dovich (SZ) selected galaxy clusters detected with signal-to-noise ratio >4 in 13211deg^2^ of sky surveyed by the... -
Galaxy clusters from the DESI surveys. I.
Based on the photometric redshift catalog of Zou+ (2019ApJS..242....8Z), we apply a fast clustering algorithm to identify 540432 galaxy clusters at z<=1 in the DESI legacy... -
Cluster galaxy circular velocity function
We present galaxy circular velocity functions (GCVFs) for 34 low-redshift (z<~0.15) clusters identified in the Sloan Digital Sky Survey (SDSS, Cat. ), for 15 clusters drawn... -
HI obs. of low surface brightness dwarf gal.
According to the cold dark matter (CDM) hierarchical clustering theory of galaxy and large-scale structure formation, there should be numerous low-mass dark matter haloes... -
Large-scale clumpy structure in Lynx region
We report the discovery of a probable large-scale structure composed of many galaxy clumps around the known twin clusters at z=1.26 and 1.27 in the Lynx region. Our analysis is... -
H{alpha} survey of cluster galaxies
We have extended our H{alpha} objective prism survey of eight low-redshift clusters (viz. Abell 262, 347, 400, 426, 569, 779, 1367 and 1656) to include a complete sample of... -
Structure of early-type galaxies
We study the Photometric Plane (PHP), namely the relation between the effective radius r_e_, the mean surface brightness within that radius {mu}e and the Sersic index n, in...
