AbstractWe present the results of a search for nuclear X-ray activity in nearby galaxies using Chandra archival data in a sample of 62 galaxies from the Spitzer Infrared Nearby Galaxy Survey. We detect 37 nuclear X-ray sources; seven of these are new detections. Most of the nuclear X-ray sources are likely to be active galactic nuclei (AGNs). The fraction of galaxies hosting AGNs is thus about 60%, much higher than that foun ...
