The fraction of early-type galaxies that harbor an active galactic nucleus (AGN) is reasonably well constrained. These galaxies tend to be more massive, have more massive central supermassive black holes (SMBHs), and thus stronger AGN signatures which are easy to detect at optical wavelengths. Furthermore, early-type galaxies tend to be relatively free of obscuring dust and star-forming regions. Very late-type galaxies (Sc and later), however, are gas and dust rich, and tend to have much more active star formation. Coupled with smaller SMBHs yielding weaker AGN signatures, this makes identification of AGN in late-type systems extremely challenging at optical wavelengths. X-rays from such AGN, however, can penetrate this obscuring medium, and provide a way to detect AGN in late-type systems. We present here a survey of late-type galaxies, using Chandra archival x-ray images, to look for AGN candidates and constrain the AGN fraction in such systems.
