Scientific paper

Recent discovery of galaxies emitting surprisingly strong Lyman continuum at redshift z~=3 with Subaru telescope is discussed. These galaxies are brighter at 900 A˚ in their rest-frame (i.e. hydrogen ionizing radiation) than at 1600 A˚ (non-ionizing radiation). Such an extreme spectrum, which we call Lyman limit `bump', has been never expected by any spectral models of galaxies so far. Here, we show that the observed strength of the Lyman bump can be explained by a model spectrum of a galaxy which has matter-bounded nebulae photoionized by very massive (~100 Msolar) and metal-free (so-called Population III) stars. This suggests that such a primordial stellar population still exists at z~=3, rather late epoch of the cosmic evolution.
