The Chemical and Ionization Conditions in Weak Mg II Absorbers
Anand Narayanan, Jane C. Charlton, Toru Misawa +2
We present an analysis of the chemical and ionization conditions in a sample of 100 weak Mg II absorbers identified in the VLT/UVES archive of quasar spectra. Using a host of low i…
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…
A Survey of Analogs to Weak MgII Absorbers in the Present
Anand Narayanan, Jane C. Charlton, Joe R. Masiero +1
We present the results of a survey of the analogs of weak MgII absorbers (rest frame equivalent width W(2796) < 0.3 A) at 0 < z < 0.3. Our sample consisted of 25 HST/STIS echelle q…
