核膨胀X射线源群的对应物

Counterparts to the Nuclear Bulge X-ray source population

Andrew J. Gosling, Reba M. Bandyopadhyay, Katherine M. Blundell, Phil Lucas

摘要:

我们提出了一个初始匹配的源位置的钱德拉核膨胀X射线源的新UKIDSS-GPS近红外调查的核膨胀。尽管如此,由于该区域极其拥挤的性质,这项任务变得困难,我们找到了约50%的X射线源的候选对应物。我们发现,在J-波段的候选对应的X射线源的检测优先选择那些候选对应的前景,而候选对应的只在H和K-波段的检测更有可能是核膨胀源。我们讨论了计划对这些候选对应方采取的后续行动。

英文摘要:

We present an initial matching of the source positions of the Chandra Nuclear Bulge X-ray sources to the new UKIDSS-GPS near-infrared survey of the Nuclear Bulge. This task is made difficult by the extremely crowded nature of the region, despite this, we find candidate counterparts to ~50% of the X-ray sources. We show that detection in the J-band for a candidate counterpart to an X-ray source preferentially selects those candidate counterparts in the foreground whereas candidate counterparts with only detections in the H and K-bands are more likely to be Nuclear Bulge sources. We discuss the planned follow-up for these candidate counterparts.
