THE GALAXY CONTENT OF SDSS CLUSTERS AND GROUPS [PDF]
The Astrophysical Journal, 2009 Imaging data from the Sloan Digital Sky Survey are used to characterize the population of galaxies in groups and clusters detected with the MaxBCG algorithm. We investigate the dependence of Brightest Cluster Galaxy (BCG) luminosity, and the distributions of satellite galaxy luminosity and satellite color, on cluster properties over the redshift range ...

AEGIS: Chandra Observation of DEEP2 Galaxy Groups and Clusters [PDF]
, 2006 We present a 200 ksec Chandra observation of seven spectroscopically selected, high redshift (0.75 < z < 1.03) galaxy groups and clusters discovered by the DEEP2 Galaxy Redshift Survey in the Extended Groth Strip (EGS). X-ray emission at the locations of

The XMM Large-Scale Structure survey: an initial sample of galaxy groups and clusters to a redshift z < 0.6★ [PDF]
, 2005 We present X-ray and optical spectroscopic observations of 12 galaxy groups and clusters identified within the X-ray Multi-Mirror (XMM) Large-Scale Structure (LSS) survey.

Triggering of merger‐induced starbursts by the tidal field of galaxy groups and clusters [PDF]
, 2007 Star formation in galaxies is for a part driven by galaxy mergers. At low redshift, star formation activity is low in high-density environments like groups and clusters, and the star formation activity of galaxies increases with their isolation.

Entropy Evolution in Galaxy Groups and Clusters: a Comparison of External and Internal Heating [PDF]
, 2001 The entropy in hot, X-ray-emitting gas in galaxy groups and clusters is a measure of past heating events, except for the entropy lost by radiation from denser regions.

Velocity-dependent self-interacting dark matter from groups and clusters of galaxies [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We probe the self-interactions of dark matter with relaxed galaxy groups and clusters using observational data from strong and weak lensing and stellar kinematics.

How special are brightest group and cluster galaxies? [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 Abstract We use the Sloan Digital Sky Survey (SDSS) to construct a sample of 625 brightest group and cluster galaxies (BCGs) together with control samples of non-BCGs matched in stellar mass, redshift and colour. We investigate how the systematic properties of BCGs depend on stellar mass and on their privileged location near the cluster ...

A Census of Baryons in Galaxy Clusters and Groups [PDF]
, 2007 We determine the contribution of stars in galaxies, intracluster stars, and the intracluster medium to the total baryon budget in nearby galaxy clusters and groups. We find that the baryon mass fraction (f_b) within r500 is constant for systems with M500

HEATING THE HOT ATMOSPHERES OF GALAXY GROUPS AND CLUSTERS WITH CAVITIES: THE RELATIONSHIP BETWEEN JET POWER AND LOW-FREQUENCY RADIO EMISSION [PDF]
, 2011 We present scaling relations between jet power and radio power measured using the Giant Metrewave Radio Telescope (GMRT), Chandra, and XMM-Newton, for a sample of nine galaxy groups combined with the Bîrzan et al. sample of clusters. Cavity power is used
