Infrared-selected 'warm' galaxies observed in X-rays
Abstract
Infrared, optical, and X-ray observations are presented for a sample of 'warm' infrared selected galaxies listed in the IRAS Point Source Catalog. These galaxies have also been observed serendipitously in X-rays by the Einstein Observatory. From low-resolution optical spectra, it is found that all have emission lines, indicating a Seyfert or H II region type nucleus. Many of these galaxies were previously uncataloged. Based on the X-ray detection rate of this sample, it is concluded that large numbers of warm IRAS Seyfert 1-1.9 galaxies may be detectable in X-rays by future surveys such as Rosat.
