Velocity Dispersion of 335 Galaxy Clusters Selected from the Sloan Digital Sky Survey: Statistical Evidence for Dynamical Interaction, and Against Ram-Pressure Stripping [PDF]
Mon.Not.Roy.Astron.Soc. 359 (2005) 1415-1420, 2005 There has been plenty of observational evidence of cluster galaxy evolution. However, it has been difficult to identify the origin of the cluster galaxy evolution. Here we show that gravitational interaction/friction between galaxies is the statistically dominant physical mechanism responsible for the cluster galaxy evolution, and that the well-favored

Galaxy Properties in Clusters: Dependence on the Environment and the Cluster Identification Techniques [PDF]
, 2009 We investigate the dependence of several galaxy properties on the environment and cluster identification techniques. We select clusters of galaxies from two catalogues based on the SDSS: the ROSAT-SDSS Galaxy Cluster Survey, and the MaxBCG Catalogue. Based on a volume limited sample of galaxies drawn from the spectroscopic DR5 SDSS, we constructed sub ...

Detection of a Star Forming Galaxy in the Center of a Low-Mass Galaxy Cluster [PDF]
, 2018 Brightest Cluster Galaxies (BCGs) residing in the centers of galaxy clusters are typically quenched giant ellipticals. A recent study hinted that star-forming galaxies with large disks, so-called superluminous spirals and lenticulars, are the BCGs of a subset of galaxy clusters.

Cosmology with Clusters of Galaxies [PDF]
, 2008 In this Chapter I review the role that galaxy clusters play as tools to constrain cosmological parameters. I will concentrate mostly on the application of the mass function of galaxy clusters, while other methods, such as that based on the baryon fraction, are covered by other Chapters of the book.

Statistics of Galaxy Clustering [PDF]
, 2006 In this introductory talk we will establish connections between the statistical analysis of galaxy clustering in cosmology and recent work in mainstream spatial statistics. The lecture will review the methods of spatial statistics used by both sets of scholars, having in mind the cross-fertilizing purpose of the meeting series.

The Dependence of Globular Cluster Number on Density for Abell Cluster Central Galaxies [PDF]
, 1997 A study of the globular cluster systems of 23 brightest, or central, galaxies in 19 Abell clusters has recently been completed. This Letter presents some of the newly discovered correlations of the globular cluster specific frequency $S_N$ in these galaxies with other galaxy and cluster properties and puts forth an interpretation of these results. $S_N$

Infant Galaxy Clusters at Low Redshifts? [PDF]
, 2003 The population and population composition of galaxies in galaxy clusters at present reflect the mass of the clusters and the mass growth of the galaxies in the past. We investigate them for six clusters. We show that galaxies in massive clusters stopped growing at redshifts of ~4. Moreover, we find that some small galaxy clusters (groups) have too many

Detection of a Superluminous Spiral Galaxy in the Heart of a Massive Galaxy Cluster [PDF]
, 2022 It is well established that brightest cluster galaxies (BCGs), residing in the center of galaxy clusters, are typically massive and quenched galaxies with cD or elliptical morphology. An optical survey suggested that an exotic galaxy population, superluminous spiral and lenticular galaxies could be the BCGs of some galaxy clusters.
