RUNAWAY STARS AND THE ESCAPE OF IONIZING RADIATION FROM HIGH-REDSHIFT GALAXIES

Approximately 30% of all massive stars in the Galaxy are runaways with velocities exceeding 30 km s super(-1). Their high speeds allow them to travel ~0.1-1 kpc away from their birthplace before they explode at the end of their several Myr lifetimes. At high redshift, when galaxies were much smaller...
