Dataset of Classified Chandra Sources in Globular Clusters

Steven Chen, Oleg Kargaltsev, Hui Yang +1

We present a collection of classified X-ray sources in Globular Clusters (GCs) observed by the Chandra X-ray Observatory (CXO), including active binaries, cataclysmic variables, mi…

Chandra X-ray Observatory Observations of 13 Fermi LAT Sources

Blagoy Rangelov, Hui Yang, Brice Williams +3

In the latest data release from the Fermi -ray Space Telescope (the 4th Fermi LAT 14 yr Catalog, or 4FGL), more than 50% of the Galactic sources are yet to be identified. We obs…

Population of X-ray Sources in the Intermediate-Age Cluster NGC 3532: a Test Bed for Machine-Learning Classification

Steven Chen, Oleg Kargaltsev, Hui Yang +4

Open clusters are thought to be the birth place of most stars in the Galaxy. Thus, they are excellent laboratories for investigating stellar evolution, and X-ray properties of vari…

Classifying Unidentified X-ray Sources in the Chandra Source Catalog Using a Multiwavelength Machine-learning Approach

Hui Yang, Jeremy Hare, Oleg Kargaltsev +3

The rapid increase in serendipitous X-ray source detections requires the development of novel approaches to efficiently explore the nature of X-ray sources. If even a fraction of t…
