Physical conditions in metal line systems toward Q1037-2704: Evidence for superclustering at z=2
Yannick Lespine, Patrick Petitjean
We present a high spectral resolution optical spectrum of the bright quasar Q~1037-2704. The large number of absorption systems suggests the presence of an intervening supercluster…
