Deficiency of Broad Line AGNs in Compact Groups of Galaxies
M. A. Martinez, A. del Olmo, R. Coziol +1
Based on a new survey of AGN activity in Compact Groups of Galaxies, we report a remarkable deficiency of Broad Line AGNs as compared to Narrow Line AGNs. The cause of such deficie…
Nuclear activity in galaxy pairs: a spectroscopic analysis of 48 UZC-BGPs
Paola Focardi, Valentina Zitelli, Silvia Marinoni
Galaxy pairs are ideal sites in which to investigate the role of interaction on nuclear activity. For this reason we have undertaken a spectroscopic survey of a large homogeneous s…
A new sample of bright galaxy pairs in UZC
P. Focardi, V. Zitelli, S. Marinoni +1
We present a new sample of bright galaxy pairs extracted applying an objective selection code to UZC catalog.The sample is volume limited to M = -18.9 +5 log and c…
Optical properties of the NGC 5328 group of galaxies
R. Gruetzbauch, F. Annibali, A. Bressan +4
We present the results of a photometric and spectroscopic study of seven members of the NGC 5328 group of galaxies, a chain of galaxies spanning over 200 kpc (H_0 = 70 km/s/Mpc). W…
Small-scale systems of galaxies. II. Properties of the NGC 4756 group of galaxies
R. Gruetzbauch, B. Kelm, P. Focardi +3
We present results from a study of the NGC 4756 group which is dominated by the elliptical galaxy NGC 5746. The characteristics of the group are investigated through (a) the detail…
Single Star-forming galaxies and Star-forming galaxies in SF+SF and mixed pairs
B. Kelm, P. Focardi
We compare the SFR of single star-forming galaxies with the SFR of star-forming galaxies in pairs. Volume-limited samples are compared selected from the 2dFGRS, applying a maximum…
