VizieR Online Data Catalog: Extragalactic X-ray binaries catalog (Inoue+, 2021)

X-ray source information is extracted from the latest Chandra source catalog. The Chandra X-ray observatory, launched in 1999 July 23, observes the X-ray sky in the energy range between 0.1-10keV over a field of view of ~60-250arcmin². Chandra achieves a sub-arcsecond on-axis point spread function (Weisskopf et al. 2000, Proc. SPIE, 4012, 2; 2002PASP..144....1W). These instrumental capabilities allow the detection sources with low confusion and good astrometry. On 2019 October 24, a new version of the Chandra source catalog (CSC2) was released (Evans et al. 2010ApJS..189...37E, Cat. IX/45, IX/57; 2020, BAAS, 52(1), 154.05), which contains 317167 unique X-ray sources in the sky including 1432324 per observation data sets.

We construct a new catalog of XRBs in external galaxies utilizing the latest Chandra (Evans et al. 2010ApJS..189...37E, Cat. IX/45, IX/57, 2020, BAAS, 52(1), 154.05) source catalog. We match these X-ray source catalogs with two nearby galaxy catalogs: the LVG catalog and the IRAS catalog. Our catalog contains 4430 XRBs, including 378 ULXs, associated with 237 galaxies. Of those XRB-hosting galaxies, ~84% are late-type.
