Cluster Galaxies at High Redshift

1988
Modern CCD instrumentation has made it possible to obtain photometric and spectroscopic data on normal galaxies in clusters at redshifts up to nearly unity. In this paper we discuss a survey for such clusters and preliminary spectroscopic results for galaxies in a sample of 7 clusters near redshift 0.5, and another at z=0.75.

The High Redshift 3CR Radio Galaxies: CD Galaxies in High Redshift Clusters

1998
The old stellar populations of the 3CR radio galaxies at redshifts z ∼ 1 have been investigated using the HST and UKIRT. The radial intensity profiles of the galaxies are well matched out to radii τ ∼ 35kpc by de Vaucouleurs’ law with no requirement for an additional point source in all but two cases (3C22 and 3C41).

Evolution of Disk Galaxies in High-Redshift Clusters

1986
We propose an evolutionary scenario for spiral galaxies in rich, compact clusters. Interactions with the environment, probably dominated by the processes in the hot gaseous intergalactic medium, remove the gas from the disks of blue objects infalling into cluster cores from outer layers. Predictions are made for UBV colors of cluster spirals versus the

The Influence of environment on high-redshift cluster galaxies

2018
Les proprietes des galaxies, comme la couleur, le taux de formation stellaire et la morphologie, sont influencees par l'environnement dans lequel elles resident. Plus particulierement, les environnements des amas de galaxies se montrent tres efficaces pour etouffer la formation stellaire et alterent d'autres proprietes galactiques observees, bien que ...

The growth of massive galaxies and clusters at high redshift

2013
Massive galaxies and galaxy clusters gain much of their mass by merging with their neighbors; this hierarchical structure formation is the foundation of our understanding of galaxy evolution. Nevertheless, the detailed evolutionary processes needed to form the structures we see in the local Universe remain poorly understood.
