2016ApJS..222...12G An Extreme Luminous X-ray Source Catalog Based on Chandra ACIS Observations Gong, Hang; Liu, Jifeng; Maccarone, Thomas 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 {L}_{{X_}}\gt 3x {10}^40^ {erg} {{{s}}}^-1^ from 93 galaxies or 41 HLX candidates with {L}_{{X_}}\gt 1x {10}^41^ {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. Key words: catalogs, galaxies: general, X-rays: binaries, X-rays: galaxies
