The Absorption Signature of Six MgII-Selected Systems Over 0.5<z<0.9
Jie Ding, Jane C. Charlton, Christopher W. Churchill
We present the following results of photoionization modeling of six MgII-selected absorption systems, at redshift 0.5 < z 0.9, along lines of sight toward three quasars: PG 1241+17…

The Absorption Signatures of Dwarf Galaxies: The z=1.04 Multicloud Weak MgII Absorber toward PG 1634+706
Stephanie G. Zonak, Jane C. Charlton, Jie Ding +1
We analyze high resolution spectra of a multi--cloud weak [defined as W_r(MgII) < 0.3 A] absorbing system along the line of sight to PG 1634+706. This system gives rise to a partia…
