标题： An Infrared Imaging Survey of the Faint Chandra Sources near the Galactic Centre

摘要： 我们展示了从2001年钱德拉ACIS-I巡天中发现的银河系中心(GC)方向一些暗弱硬X射线源的近红外成像(Wang等, 2002)。这大约800个离散源代表了银河系内一个重要的且之前未被探测到的群体。基于我们对77个X射线源的VLT观测，我们在样本中的钱德拉源中识别出约75%的K波段候选对应体。大多数候选对应体的近红外星等和颜色与高度消光的恒星一致，表明大部分钱德拉源可能是位于或接近GC的吸积双星。 显示英文摘要

摘要： We present near-IR imaging of a sample of the faint, hard X-ray sources discovered in the 2001 Chandra ACIS-I survey towards the Galactic Centre (GC) (Wang et al. 2002). These ~800 discrete sources represent an important and previously undetected population within the Galaxy. From our VLT observations of 77 X-ray sources, we identify candidate K-band counterparts to 75% of the Chandra sources in our sample. The near-IR magnitudes and colours of the majority of candidate counterparts are consistent with highly reddened stars, indicating that most of the Chandra sources are likely to be accreting binaries at or near the GC.
