Clues on the Evolution of Cluster Galaxies From The Analysis of Their Orbital Anisotropies
A. Biviano, P. Katgert, T. Thomas +1
We study the evolution of galaxies in clusters by the analysis of a sample of about 3000 galaxies, members of 59 clusters from the ESO Nearby Abell Cluster Survey (ENACS). We disti…
Parsec-scale structure in galactic disk and halo, from diffuse radio polarization
M. Haverkorn, P. Katgert, A. G. de Bruyn
We present multi-frequency polarization observations of the diffuse radio synchrotron background modulated by Faraday rotation. No total intensity is observed, indicating that tota…
Structure in the local Galactic ISM on scales down to 1 pc, from multi-band radio polarization observations
M. Haverkorn, P. Katgert, A. G. de Bruyn
We discuss observations of the linearly polarized component of the diffuse galactic radio background. These observations, with an angular resolution of 4', were made with the Weste…
The ESO Nearby Abell Cluster Survey VI. Spatial distribution and kinematics of early- and late-type galaxies
P. A. M. de Theije, P. Katgert
We used the galaxy spectra obtained in the ESO Nearby Abell Cluster Survey (ENACS) to separate early- and late-type galaxies in the ENACS clusters, by applying a Principal Componen…
The ESO Nearby Abell Cluster Survey: Kinematics of Galaxies in Clusters
A. Biviano, A. Mazure, C. Adami +4
We summarize several results based on the velocity data-set for cluster galaxies provided by ENACS (the ESO Nearby Abell Cluster Survey). We describe the distribution of velocity d…
The ESO Nearby Abell Cluster Survey: Properties of the Galaxies
P. Katgert, C. Adami, P. de Theije +3
In this paper we summarize the main properties of the ENACS (the ESO Nearby Abell Cluster Survey), which was one of the ESO Keyprogrammes carried out in the first half of the 1990'…
