The environment of Seyferts, Liners and HII galaxies in a Complete AGN sample
V. Zitelli, B. Kelm, P. Focardi +1
We use a complete AGN sample (Ho et al. 1997) to study the environment of Seyferts, LINERs and HII galaxies. For each AGN we search for companions in the UZC redshift catalogue and…
Star-forming galaxies in the 2dFGRS
B. Kelm, G. Sorrentino, P. Focardi
We examine the environment of star-forming galaxies selected in the 2dFGRS. We find that bright star-forming galaxies display a significant deficit of faint neighbours relative to…
The ESO Nearby Abell Cluster Survey. III. Distribution and Kinematics of Emission-Line Galaxies
A. Biviano, P. Katgert, A. Mazure +4
We have studied the frequency of occurrence, the kinematics and the spatial distribution of Emission-Line Galaxies (ELG) in clusters in the ESO Nearby Abell Cluster Survey (ENACS).…
The ESO Nearby Abell Cluster Survey. I. Description of the Dataset and Definition of Physical Systems
P. Katgert, A. Mazure, J. Perea +1
Summary - We describe the results of the ESO Key-programme on `Structure and Dynamics of Rich Galaxy Clusters' (or ENACS). The final database contains a total of 5634 galaxies in t…
The Kinematics of Emission-Line Galaxies in Clusters from ENACS
A. Biviano, P. Katgert, A. Mazure +3
Summary - By using the data from the ESO Nearby Abell Cluster Survey (ENACS), we have studied the properties of emission-line galaxies (ELG) in clusters. The fraction of ELG in clu…
The Kinematics of Emission-Line Galaxies in Clusters from ENACS
A. Biviano, P. Katgert, A. Mazure +3
By using the ENACS data, we have studied the properties of emission-line galaxies (ELG) in clusters. The fraction of ELG in clusters is 16~%; this fraction is slightly dependent on…
