Building the Largest Catalogue of Intermediate Redshift ULXs: Evolution out to z=0.3
Abstract
We propose a Chandra archival research project to build the largest catalog of intermediate redshift (z<0.3) ultra-luminous X-ray sources (ULXs). We will accomplish this by using our astrometric procedure that is optimized for registering Chandra/ACIS datasets with optical imaging, allowing us to resolve offset X-ray sources down to sub-arcsecond angular separations. Based on our pilot study, this project will increase the known number of intermediate redshift ULXs by a factor of over 30, and we will publish it for broad use by the community. As demonstrated by our preliminary results, analysis of this uniformly selected sample will permit an understanding of how the ULX population evolves out to z=0.3 and thus a deeper knowledge of their formation mechanisms and physical nature.
