摘要：
The Galactic Ridge X-ray Emission (GRXE) is an apparently extended emission along the Galactic Plane. Its origin has been a mystery for a long time. However, recent study revealed that about 80% of the GRXE is consist of dim X-ray point sources. It raises a new question, what are the populations of them? In this study, we identified X-ray point sources constituting the GRXE with near-infrared (NIR) and obtained NIR spectra. The spectra suggest that almost the sources are late-type stars.
