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'…
The use of Minimal Spanning Tree to characterize the 2D cluster galaxy distribution
C. Adami, A. Mazure
We use the Minimal Spanning Tree to characterize the aggregation level of given sets of points. We test 3 distances based on the histogram of the MST edges to discriminate between…
ENACSVII, Galaxy density profiles of rich clusters of galaxies
C. Adami, A. Mazure, P. Katgert +1
We have analyzed the projected galaxy distributions in a subset of the ENACS/ COSMOS cluster sample. We made Maximum-Likelihood fits to the distribution of COSMOS galaxies for 4 th…
Deep probing of the Coma cluster
C. Adami, R. C. Nichol, A. Mazure +3
As a continuation of our study of the faint galaxy luminosity function in the Coma cluster of galaxies, we report here on the first spectroscopic observations of very faint galaxie…
Count laws and projection effects in clusters of galaxies
C. Adami, P. Amram, G. Comte
We show that a 2D projection is representative of its corresponding 3D distribution at a confidence level of 90 % if it follows a King profile and if we consider the whole spatial…
