PKS 0537-286: a high-redshift QSO with an extreme Lyman-continuum cutoff.
Abstract
Spectroscopic observations of the 20th mag object identified with the radio source PKS 0537-286 are reported. The object is shown to have an emission redshift of 3.11, a prominent absorption system at a redshift of 2.976, and a strong discontinuity at the Lyman-continuum edge in the absorption system.
