Abstract:
The X-ray and gamma-ray observatory INTEGRAL has discovered large
numbers of new hard X-ray sources, many of which are believed to be
high mass X-ray binaries. However, for a significant fraction, their
counterparts remain unidentified.
We explore the use of photometric catalogues to find optical
counterparts to high mass X-ray binaries and search for objects likely
to be early-type stars within the error circles of several INTEGRAL
sources.
