SUMMARY:Extragalactic Fast X-ray Transients - Franz Bauer (PUC\, Chile)

DESCRIPTION:The discovery of two fast X-ray transients in the Chandra Deep
  Field-South\, potentially associated with the merger of neutron stars\, a
 nd hence the X-ray counterparts of GW170817-like events\, has sparked grea
 t interest in this novel type of transient.  We undertake a search for sim
 ilar objects among a database of ~220\,000 serendipitous X-ray sources in 
 the Chandra Source Catalog (CSC 2.0)\, cross-matching against optical and 
 infrared catalogs. Using two distinct methods\, we find a handful of poten
 tial candidates. These new candidates provide up to an order of magnitude 
 increase in source statistics and should allow better constraints on the e
 mission mechanisms for this emerging transient class. I will discuss the b
 asic properties of the sample and what these might imply about their origi
 n.
