Physical Sciences: Multiple Redshifts in QSOs

Abstract

Four QSOs (PHL 957, Ton 1530, Parkes 0237–23, and 4C 05.34) are now known with complex absorption spectra; these have been interpreted as objects with multiple redshifts. It is disturbing that even with the use of up to 10 redshifts per object, 20% or more of the absorption lines which are definitely present with strength 2 or greater remain unidentified.
