Abstract

Using Chandra archive data we conduct a thorough survey of luminous X-ray sources. We directly analyze about 9400 ACIS Observations and cross-correlate the X-ray sources with 77,000 galaxies within 250 Mpc. The final catalog includes 119 unique luminous X-ray source candidates with LX > 3 × 1040 erg s-1 from 93 galaxies or 41 HLX candidates with LX > 3 × 1040 erg s-1 from 35 galaxies. We derive a moderate contamination rate due to foreground or background sources. We also cross-correlate the catalog with FIRST, perform variability and periodicity tests, and analyze one HLX candidate in particular. Our catalog could be a starting point to perform follow-up observations.
