Ultraluminous X-ray sources in local Universe
Listed in IVOA Registry (Virtual Observatory)
Using the Chandra Source Catalog 2.0 and a newly compiled catalogue of galaxies in the local Universe, we deliver a census of ultraluminous X-ray source (ULX) populations in nearby galaxies.
Description
We find 629 ULX candidates in 309 galaxies with distance smaller than 40Mpc. The foreground/background contamination is ~20 per cent.
The ULX populations in bona fide star-forming galaxies scale on average with star formation rate and stellar mass (M_*_) such that the number of ULXs per galaxy is 0.45^+0.06^_-0.09_xSFR/(M_{sun}_/yr)+3.3^+3.8^_-3.2_xM_*_/M_{sun}_. The scaling depends strongly on the morphological type. This analysis shows that early spiral galaxies contain an additional population of ULXs that scales with M_*_.

We also confirm the strong anticorrelation of the ULX rate with the host galaxy's metallicity. In the case of early-type galaxies, we find that there is a non-linear dependence of the number of ULXs with M_*_, which is interpreted as the result of star formation history differences. Taking into account age and metallicity effects, we find that the predictions from X-ray binary population synthesis models are consistent with the observed ULX rates in early-type galaxies, as well as spiral/irregular galaxies.
