Abstract

Far-ultraviolet observations of the nearby low-mass star-forming galaxy J0925+1403 show that the galaxy is leaking ionizing radiation with an escape fraction of about 8 per cent, which is sufficient to ionize intergalactic medium material that is about 40 times as massive as the stellar mass of the galaxy.
