NGC 5128 Chandra X-ray point sources
Listed in IVOA Registry (Virtual Observatory)
Very Large Telescope images in BVI are used to identify the optical counterparts to bright Chandra X-ray points sources discovered by Kraft and coworkers (2001, Cat. <J/ApJ/560/675>).
Description
Of a total of 111 X-ray point sources with L_X_>2x10^36^erg/s present in a 56arcmin^2^ field centered on this galaxy, 58 have optical counterparts. On the basis of the sizes, optical magnitudes, and colors, 20 new globular cluster counterparts of X-ray sources are identified, and three are identified on the basis of their sizes.
This brings the total number of globular cluster X-ray sources in this galaxy to 33 and establishes that 30% of the X-ray point sources in NGC 5128 are associated with globular clusters.
