Exploring the Nature of Weak Chandra Sources near the Galactic Centre
ArXiv astro-ph/0501327 (2005)
Abstract:
We present results from the first near-IR imaging of the weak X-ray sources discovered in the Chandra/ACIS-I survey (Wang et al. 2002) towards the Galactic Centre (GC). These ~800 discrete sources, which contribute significantly to the GC X-ray emission, represent an important and previously unknown population within the Galaxy. From our VLT observations we will identify likely IR counterparts to a sample of the hardest sources, which are most likely X-ray binaries. With these data we can place constraints on the nature of the discrete weak X-ray source population of the GC.Exploring the Nature of Weak Chandra Sources near the Galactic Centre
