Discovery of a Transient ULX in M83
Abstract
We report our discovery of a transient ultraluminous X-ray source in the inner disk of the spiral galaxy M83 (d = 4.5 Mpc). Our recent Chandra/ACIS observations of this galaxy (60 ks on 2010 December 23 and 100 ks on 2010 December 25) show a bright point-like source about 1 arcmin (1.3 kpc) to the east of the nucleus, at R.A.(J2000) = 13h 37m 05.143s and Dec. (J2000) = -29d 52m 06.9s (0.5 arcsec uncertainty).
