We construct a new catalog of extragalactic X-ray binaries (XRBs) by matching the latest Chandra source catalog with local galaxy catalogs. Our XRB catalog contains 4430 XRBs hosted by 237 galaxies within ∼130 Mpc. As XRBs dominate the X-ray activity in galaxies, the catalog enables us to study the correlations between the total X-ray luminosity of a galaxy L_X,tot, star formation rate {dot}ρ_*, and stellar mass M_*. As previously reported, L_X,tot is correlated with {dot}ρ_* and M_*. In particular, we find that there is a fundamental plane in those three parameters; logL_X,tot=38.80^+0.09_–0.12+log({dot}ρ_* + αM_*, where α = (3.36 ± 1.40) x 10^–11 yr^–1. In order to investigate this relation, we construct a phenomenological binary population synthesis model. We find that the high-mass XRB and low-mass XRB fraction in formed compact object binary systems is ∼9% and 0.04%, respectively. Utilizing the latest XMM-Newton and Swift X-ray source catalog data sets, additional XRB candidates are also found, resulting in a total of 5757 XRBs hosted by 311 galaxies.
