Utilized the XMM-Newton data archives to build a large, clean( with least confusion and contamination) X-Ray galaxy catalog. Obtained multiwavelength data for these X-ray galaxies using the following sky survey catalogs: SDSS, Legacy, GALEX, 2MASS, PS, and WISE. Nway technique was used to do the crossmatching of data and the catalog was built using Astropy.
