Probing Large-scale UV Background Inhomogeneity Associated with Quasars using Metal Absorption
Sean Morrison, Matthew M. Pieri, Debopam Som +1
We study large-scale UV background inhomogeneity in three-dimensions associated with the observed quasar populations at high redshift. We do this by measuring metal absorption thro…

Metals and a Search for Molecules in the Distant Universe: Magellan MIKE Observations of sub-DLAs at 2<z<3
Suraj Poudel, Varsha P. Kulkarni, Debopam Som +1
We present abundance measurements of the elements Zn, S, O, C, Si and Fe for four sub-DLAs at redshifts ranging from z=2.173 to z=2.635 using observations from the MIKE spectrograp…
