X-rays from a peculiar nucleus galaxy NGC 2196
Abstract
Detection of a new X-ray source with the Einstein Observatory and its identification with the early type spiral (Sa) galaxy NGC 2196 (MCG 4-15-14), a member of Sersic's (1973) list of peculiar nuclei galaxies is reported. The X-ray luminosity of the galaxy is found to approximately 2 x 10 to the 40th erg/sec which is an order of magnitude higher compared to that of the normal spiral galaxies but comparable to that observed from weakly-active galaxies. The optical and X-ray characteristics of the galaxy are discussed and compared with those of the other normal and weakly-active galaxies.
