Detection of high Lyman continuum leakage from four low-redshift compact star-forming galaxies

Original language description

Following our first detection reported in Izotov et al., we present the detection of Lyman continuum (LyC) radiation of four other compact star-forming galaxies observed with the Cosmic Origins Spectrograph (COS) onboard the Hubble Space Telescope. These galaxies, at redshifts of z similar to 0.3, are characterized by high emission-line flux ratios [O III] lambda 5007/[O II] lambda 3727 greater than or similar to 5. The escape fractions of the LyC radiation f(esc)(LyC) in these galaxies are in the range of similar to 6-13 per cent, the highest values found so far in low-redshift star-forming galaxies. Narrow double-peaked Ly alpha emission lines are detected in the spectra of all four galaxies, compatible with predictions for LyC leakers. We find escape fractions of Ly alpha, f(esc)(Ly alpha) similar to 20-40 per cent, among the highest known for Ly alpha emitting galaxies.
