An X-ray Study of a Tidal Disruption Event in an AGN Host Galaxy
Abstract
The latest generation of wide-field time-domain surveys have discovered new rare types of transients including luminous transients coincident with the nuclei of AGN galaxies that could be due to superluminous supernovae, tidal disruption events, or extreme AGN activity. We propose to obtain a Chandra observation of PS16dtm, one of the first members of this class of luminous nuclear transients in galaxies with AGN. The disappearance of X-ray emission relative to an archival detection of the AGN suggests that PS16dtm is a tidal disruption event in which the accretion of the stellar debris obscures the X-ray emission from the AGN. Chandra observations of PS16dtm will allow us to determine if and when the X-rays reappear, providing a crucial test of this scenario.
