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 کاملEisily Looking for Distant Galaxy Clusters
We present a new algorithm to search for distant clusters of galaxies on catalogues deriving from imaging data, as those of the ESO Imaging Survey. We discuss the advantages of our technique relative to the ones developed before and present preliminary results of its application to the I–band data of the survey’s
متن کاملX-ray Surveys of Distant Galaxy Clusters
I review recent observational progress in the search for and study of distant galaxy clusters in the X-ray band, with particular emphasis on the evolution of the abundance of X-ray clusters out to z ∼1. Several on-going deep X-ray surveys have led to the discovery of a sizeable population of clusters at z > 0.5 and have the sensitivity to detect clusters beyond redshift one. These surveys have ...
متن کاملInternal kinematics of spiral galaxies in distant rich galaxy clusters
We present our project on galaxy evolution in the environment of distant rich clusters aiming at disentangling the importance of specific interaction and galaxy transformation processes from the hierarchical evolution of field galaxies. Spatially resolved MOS spectra were gained with VLT/FORS to analyze the internal kinematics of disk galaxies. First results are shown for the clusters MS 1008.1...
متن کاملEccentricity Evolution in Simulated Galaxy Clusters
Strong cluster eccentricity evolution for z ≤ 0.13 has appeared in a variety of observational data sets. We examine the evolution of eccentricity in simulated galaxy clusters using a variety of simulation methodologies, amplitude normalizations, and background cosmologies. We do not find find significant evolution for z < 0.1 in any of our simulation ensembles. We suggest a systematic error in ...
