X-Ray and Infrared Selected AGN. II. Optical Spectroscopy

In a search for obscured active galactic nuclei we selected 144 x-ray/infrared emitting galaxies. Optical spectroscopy of this sample is presented. A classification according to the nuclear activity shows that 28 are AGN, 39 are transition-type objects and 44 are H II region-like galaxies. Three of the 28 AGN are Seyfert 1 galaxies and the others are of Type 2. We suggest that the objects identified as narrow line AGN are obscured Seyfert 1. Most of the observed galaxies are seen edge-on, indicating that dust may have a flattened distribution coplanar to the disk of the parent galaxy. With the inclusion of the newly identified AGN, the sample of the x-ray emitting Seyfert 2 galaxies is fairly complete above a flux limit of log F_HX_ ~ -10.8.
