Discovery of three new near-pristine absorption clouds at -4.4
P. Frédéric Robert, Michael T. Murphy, John M. O'Meara +2
We report the discovery of three new "near-pristine" Lyman Limit Systems (LLSs), with metallicities ~1/1000 solar, at redshifts 2.6, 3.8 and 4.0, with a targeted survey at the Keck…
