The Cluster M/L and the Value of Omega_m
H. Andernach, M. Plionis, O. L'opez-Cruz +2
From an up-to-date compilation of ACO cluster redshifts and velocity dispersions we extract a homogeneous sample of 459 clusters with robust velocity dispersion. Using the virial t…
Dwarf Galaxies in Clusters: the Effects of a Violent Environment
Omar Lopez-Cruz, H. K. C. Yee
Recent observations suggest that dwarf galaxies pervade the universe, for they have been encountered in large numbers in all the environments. However, we present evidence that sug…
Clusters of Galaxies at High Redshift: The LMT/GTM Perspective
Omar Lopez-Cruz, Enrique Gaztanaga
The lack of reliable cluster samples at intermediate and high redshift has motivated many optical/infrared and X-ray cluster searches. The motivation of such searches is well justi…
The Color-Magnitude Relation of Early-Type Galaxies: A Tool for Cluster Finding and Redshift Determination
H. K. C. Yee, M. D. Gladders, O. Lopez-Cruz
The color-magnitude relation (CMR) of early-type galaxies in clusters provides a powerful tool for finding clusters and determining photometric redshifts for clusters using two-fil…
