Title: Evidence consistent with the cosmological interpretation of quasar redshifts

Abstract: In this letter, the old issue of whether redshifts of quasars are of cosmological origin is investigated. We make a plot of absorption redshifts versus emission redshifts for quasars with large amounts of data. Our study shows that, almost all absorption redshifts are smaller than the corresponding emission redshifts. The relation between the absorption and emission redshifts predicted by current cosmological models is well obeyed. The result confirms that redshifts of quasars are indeed distance indicators. It might be the most obvious evidence found so far to be consistent with the cosmological interpretation of quasar redshifts.
