IRAS 09149-6206, a new Seyfert I galaxy.
Abstract
We report on the serendipitous discovery of a new type I Seyfert galaxy, IRAS 09149-6206, found during a search for planetary nebulae using the IRAS Point Source Catalogue (PSC). The optical spectrum of this galaxy shows very strong broad Balmer and Fe II emission, indicating the existence of large optical depths, while the emission spectrum from the narrow line region (NLR) is relatively weak, with only the high excitation lines present. The object presents extended [O III] emission and from the rotation curve we calculate a mass of 8 10^9^ M_sun_ within a radius of 3 kpc. It is suggested that the activity could have been triggered by interaction with a close faint companion
