Abstract:
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
∼130Mpc. 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 LX,tot, star formation rate dρ*/dt, and
stellar mass M*. As previously reported, LX,tot is correlated
with dρ*/dt and M*. In particular, we find that there is a
fundamental plane in those three parameters;
logLX,tot=38.80+0.09-0.12+log(dρ*/dt+αM*), where
α=(3.36±1.40)x10-11yr-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.
Description:
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 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 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 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.
