摘要：We present results of a multi-wavelength program to study the faint discrete X-ray source population
discovered by Chandra in the Galactic Centre (GC). From IR imaging obtained with the
VLT we identify candidate K-band counterparts to 75% of the X-ray sources in our sample. By
combining follow-up VLT K-band spectroscopy of a subset of these candidate counterparts with
the magnitude limits of our photometric survey, we suggest that only a small percentage of the
sources are HMXBs, while the majority are likely to be canonical LMXBs and CVs at the distance
of the GC. In addition, we present our discovery of highly structured small-scale (5-15′′)
extinction towards the Galactic Centre. This is the finest-scale extinction study of the Galactic
Centre to date. Finally, from these VLT observationswe are able to place constraints on the stellar
counterpart to the “bursting pulsar” GRO J1744-28.
