Toward an FRB Progenitor: Elucidating the FRB-AGN Connection with Chandra
Abstract
Fast radio bursts (FRBs) are bright, millisecond pulses discovered at radio wavelengths whose progenitors are currently unknown. There is a growing population of FRBs with sub-arcsecond localizations, which critically enable host galaxy associations and multi-wavelength observations. Of particular interest is the source of the hard radiation fields predominant in FRB hosts and their possible connection to AGN. In addition, recent constraints on periodicity have prompted a connection between FRBs and ultraluminous X-ray sources (ULXs). We request Chandra observations of a volume-limited sample of FRB host galaxies to probe the presence of AGN and bright ULXs. Understanding the AGN fraction in FRB host galaxies will provide new insight into the stellar populations that drive FRB production.
