Super-Solar Metallicity in Weak Mg II Absorption Systems at z ~ 1.7
Toru Misawa, Jane C. Charlton, Anand Narayanan
Through photoionization modeling, constraints on the physical conditions of three z ~ 1.7 single-cloud weak Mg II systems (W_r(2796) < 0.3A) are derived. Constraints are provided b…

The Advantage of Increased Resolution in the Study of Quasar Absorption Systems
Anand Narayanan, Toru Misawa, Jane C. Charlton +1
We compare a new R = 120,000 spectrum of PG1634+706 (z_QSO = 1.337,m_V = 14.9) obtained with the HDS instrument on Subaru to a R = 45, 000 spectrum obtained previously with HIRES/K…
