Evidence for the presence of dust in intervening QSO absorbers from the Sloan Digital Sky Survey
Abstract
We find evidence for dust in the intervening QSO absorbers from the spectra of QSOs in the Sloan Digital Sky Survey Data Release 1. No evidence is found for the 2175 Å feature which is present in the Milky Way dust extinction curve.
