We explore the near-infrared (NIR) K-band properties of galaxies within 93 galaxy clusters and groups using data from the Two Micron All Sky Survey. We use X-ray properties of these clusters to pinpoint cluster centers and estimate cluster masses. By stacking all these systems, we study the shape of the cluster luminosity function and the galaxy distribution within the clusters. We find that the galaxy profile is well described by the Navarro, Frenk, & White (NFW) profile with a concentration…

K-band Properties of Galaxy Clusters and Groups: Brightest Cluster Galaxies and Intracluster Light
We investigate the near-infrared K-band properties of the brightest cluster galaxies (BCGs) in a sample of 93 X-ray galaxy clusters and groups, using data from the Two Micron All Sky Survey. Our
Evolution of the K-Band Galaxy Cluster Luminosity Function and Scaling Relations
We study the evolution of two fundamental properties of galaxy clusters: the luminosity function (LF) and the scaling relations between the total galaxy number N (or luminosity) and the cluster mass
Near-Infrared Properties of Moderate-Redshift Galaxy Clusters: Luminosity Functions and Density Profiles
We present K-band imaging for 15 of the CNOC1 clusters. The extensive spectroscopic data set available for these clusters allows us to determine the cluster K-band luminosity function and density
Radio Sources in Galaxy Clusters: Radial Distribution, and 1.4 GHz and K-band Bivariate Luminosity Function
We present a statistical study of several fundamental properties of radio sources in nearby clusters (z ≤ 0.2), including the radial distribution within clusters, the radio luminosity function (RLF),
Measurement of Galaxy Cluster Sizes, Radial Profiles, and Luminosity Functions from SDSS Photometric Data
Imaging data from the Sloan Digital Sky Survey are used to measure the empirical size-richness relation for a large sample of galaxy clusters. Using population subtraction methods, we determine the
The Structure of 2MASS Galaxy Clusters
We use a sample of galaxies from the Two Micron All Sky Survey Extended Source Catalog to refine a matched filter method of finding galaxy clusters that takes into account each galaxy's position,
Galaxy cluster luminosities and colours, and their dependence on cluster mass and merger state
We study a sample of 19 galaxy clusters in the redshift range 0.15 < z < 0.30 with highly complete spectroscopic membership catalogues (to K < K*(z) + 1.5) from the Arizona Cluster Redshift Survey,
RASS-SDSS galaxy cluster survey - VII. On the cluster mass-to-light ratio and the halo occupation distribution
Aims. We explore the mass-to-light ratio in galaxy clusters and its relation to the cluster mass. Methods. We study the relations among the optical luminosity ( L op ), the cluster mass ( M 200 ) and
K-Band Properties of Well-Sampled Groups of Galaxies
We use a sample of 55 groups and six clusters of galaxies ranging in mass from 7 × 1011 to 1.5 × 1015 M⊙ to examine the correlation of the Ks-band luminosity with mass discovered by Lin and coauthors
Near-Infrared Properties of Moderate-Redshift Galaxy Clusters. II. Halo Occupation Number, Mass-to-Light Ratios, and Ωm
Using K-band imaging for 15 of the Canadian Network for Observational Cosmology (CNOC1) clusters we examine the near-infrared properties of moderate-redshift (0.19 < z < 0.55) galaxy clusters. We
