Quantifying Substructure Using Galaxy-Galaxy Lensing in Distant Clusters
We present high-resolution mass reconstructions for five massive cluster-lenses spanning a redshift range from z = 0.18–0.57 utilizing archival Hubble Space Telescope (HST) data and applying galaxy-galaxy lensing techniques. These detailed mass models were obtained by combining constraints from the observed strong and weak lensing regimes. Quantifying the local weak distortions in the shear map...
متن کامل0 Evolution of Galaxy morphologies in Clusters ∗
We have studied the evolution of galaxian morphologies from ground-based, good-seeing images of 9 clusters at z=0.09-0.25. The comparison of our data with those relative to higher redshift clusters (Dressler et al. 1997, D97) allowed us to trace for the first time the evolution of the morphological mix at a look-back time of 2-4 Gyr, finding a dependence of the observed evolutionary trends on t...
متن کامل1 99 9 Population Gradients in Galaxy Clusters at 0
We present a principal component analysis of galaxy spectra from the CNOC sample of rich X-ray luminous clusters at 0.18 < z < 0.55. Composite radial distributions of different stellar populations show strong gradients as a function of cluster-centric redshift. The composite population is dominated by evolved populations in the core, and gradually changes to one which is similar to coeval field...
متن کاملGalaxy evolution in clusters up to z = 1 . 0 ⋆
We present a combined study of the colour–magnitude relation, colour distribution and luminosity function of a sample of 24 clusters at redshifts 0.3 < z < 1. The sample is largely composed of X–ray selected/detected clusters. Most of the clusters at redshifts z < 0.6 display X–ray luminosity or richness typical of poor clusters or groups, rather than the more typical, massive clusters studied ...
متن کاملGalaxy evolution in clusters from z = 1 to z = 0
The XMM–LSS project is detecting distant clusters of low mass, quite comparable in mass to the ones in the local universe. This allows a direct comparison of galaxy properties at different redshifts in " similar " clusters. We present here first results on the evolution of the reddest galaxies in 25 clusters/groups at 0.3 < ∼ z < ∼ 1.0 and for the whole galaxy population in the same clusters. T...
