| Abstract: |
Based on Far-Ultraviolet Spectroscopic Explorer (FUSE) observations of the blue compact galaxy Haro 11, we claim the first direct detection of Lyman continuum (LyC) photon leakage from a low-redshift galaxy. Our analysis indicates a LyC photon escape fraction in the range 1−10% and favors holes in the gas over a truncated Strömgren sphere as the most likely escape mechanism. If Haro 11 may be considered to be typical of the luminous blue compact galaxies found in great numbers at high redshift, this result indicates that starburst dwarfs may play a significant role in the reionization of the early universe. |
