Resolving the X-ray emission from the Lyman continuum emitting galaxy Tol 1247-232

Abstract

Chandra observations of the nearby, Lyman-continuum (LyC) emitting galaxy Tol 1247-232 resolve the X-ray emission and show that it is dominated by a point-like source with a hard spectrum ($\Gamma =1.6\pm 0.5$) and a high luminosity ($(9\pm 2)\times 10^{40}\mathrm{erg}{\mathrm{s}}^{-1}$). Comparison with an earlier XMM-Newton observation shows flux variation of a factor of 2. Hence the X-ray emission likely arises from an accreting X-ray source: a low-luminosity AGN or one or a few X-ray binaries. The Chandra X-ray source is similar to the point-like, hard spectrum ($\Gamma =1.2\pm 0.2$), high luminosity ($10^{41}\mathrm{erg}{\mathrm{s}}^{-1}$) source seen in Haro 11, which is the only other confirmed LyC-emitting galaxy that has been resolved in X-rays. We discuss the possibility that accreting X-ray sources contribute to LyC escape.
