X-ray binaries may have helped reionize the early Universe by enabling Lyman
continuum escape. We analyzed a set of 8 local galaxies that are potential
Lyman leaking galaxies, identified by a blue color and weak emission lines,
using Chandra X-ray observations. Five of the galaxies feature X-ray sources,
while three galaxies are not significantly detected in X-rays. X-ray
luminosities were found for the galaxies and X-ray sources. Four of the
galaxies have elevated X-ray luminosity versus what would be expected based on
star formation rate and metallicity. The presence of detected X-ray sources
within the galaxies is found to correlate with the ratio of the star formation
rate estimated from the near-ultraviolet flux to that estimated from the
infrared. This implies reduced obscuration due to dust in the galaxies with
X-ray sources. These results support the idea that X-ray binaries may be an
important part of the process of reionziation.
