Archival Chandra observations of M22
Abstract
We report on a 86 ksec archival Chandra ACIS observation of the globular cluster M22 (obtained 2014-05-22). These data have been used to search for X-ray counterparts to the two black hole candidates, M22 VLA1 and M22 VLA2, identified by Strader et al (2012, Nature 490 71), and are considerably deeper than the 16 ksec ACIS exposure used for this previous work.
