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…
A Survey of Weak MgII Absorbers at 0.4 < z < 2.4
Anand Narayanan, Toru Misawa, Jane C. Charlton +1
We present results from a survey of weak MgII absorbers in the VLT/UVES spectra of 81 QSOs obtained from the ESO archive. In this survey, we identified 112 weak MgII systems within…
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…
