We plan to develop an automated multiwavelength machine-learning classification pipeline (MUWCLASS) to identify the nature of X-ray sources that have been observed by Chandra Source Catalog v2.0.
We collected multwavelength properties of all X-ray sources in these fields using the Chandra X-ray Source catalog and multiwavelength properties from Gaia-DR3, 2MASS, and WISE catalogs. We used the machine-learning approach implemented in our MUWCLASS pipeline (see e.g., Yang et al., 2022). The pipeline relies on the training dataset of ~3,000 X-ray sources that have known astrophysical types (currently these are LM-STAR, HM-STAR, YSO, AGN, LMXB, HMXB, CV, NS). We used this pipeline to classify X-ray sources whose classifications are provided in the table below.
