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…

Seyfert Galaxies in Compact Groups
P. Focardi, B. Kelm, V. Zitelli +1
We present results concerning the occurrence of Seyfert galaxies in a new large sample of Compact Groups (Focardi & Kelm 2002). Seyfert galaxies turn out to be relatively rare (<3%…
