Models of Five Absorption Line Systems Along the Line of Sight Toward PG0117+213
J. R. Masiero, J. C. Charlton, J. Ding +2
We present our investigation into the physical conditions of the gas in five intervening quasar absorption line systems along the line of sight toward the quasar PG 0117+213, with…
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…
The Multi-phase Absorption Systems Toward PG 1206+459
J. Ding, J. C. Charlton, C. W. Churchill +1
A high-resolution HST/STIS spectrum (R=30,000) is presented of the three MgII-selected absorption systems (A, B, and C, clustered within 1500km/s) at z~0.93 toward the quasar PG 12…
High Resolution STIS/HST and HIRES/Keck Spectra of Three Weak MgII Absorbers Toward PG 1634+706
J. C. Charlton, J. Ding, S. G. Zonak +3
High resolution optical (HIRES/Keck) and UV (STIS/HST) spectra, covering a large range of chemical transitions, are analyzed for three single-cloud weak MgII absorption systems alo…
A Quadruple-Phase Strong Mg II Absorber at z~0.9902 Toward PG 1634+706
J. Ding, J. C. Charlton, N. A. Bond +2
The z=0.9902 system along the quasar PG 1634+706 line of sight is a strong MgII absorber (W(2796)>0.3A) with only weak CIV absorption (it is ``CIV-deficient''). To study this syste…
