Chandra observations of the nearby, Lyman-continuum (LyC) emitting galaxy Tol1247-232 resolve the X-ray emission and show that it is dominated by apoint-like source with a hard spectrum ($\Gamma = 1.6 \pm 0.5$) and a highluminosity ($(9 \pm 2) \times 10^{40} \rm \, erg \, s^{-1}$). Comparison withan earlier XMM-Newton observation shows flux variation of a factor of 2. Hencethe X-ray emission likely arises from an accreting X-ray source: alow-luminosity AGN or one or a few X-ray binaries. The Chandra X-ray source issimilar to the point-like, hard spectrum ($\Gamma = 1.2 \pm 0.2$), highluminosity ($10^{41} \rm \, erg \, s^{-1}$) source seen in Haro 11, which isthe only other confirmed LyC-emitting galaxy that has been resolved in X-rays.We discuss the possibility that accreting X-ray sources contribute to LyCescape.
