Constraining IGM enrichment and metallicity with the C IV forest correlation function
Suk Sien Tie, Joseph F. Hennawi, Koki Kakiichi +1
The production and distribution of metals in the diffuse intergalactic medium (IGM) have implications for galaxy formation models and the baryon (re)cycling process. The relative a…
Microlensing Makes Lensed Quasar Time Delays Significantly Time Variable
S. S. Tie, C. S. Kochanek
The time delays of gravitationally lensed quasars are generally believed to be unique numbers whose measurement is limited only by the quality of the light curves and the models fo…
Eight new luminous z > 6 quasars selected via SED model fitting of VISTA, WISE and Dark Energy Survey Year 1 Observations
S. L. Reed, R. G. McMahon, P. Martini +60
We present the discovery and spectroscopic confirmation with the ESO NTT and Gemini South telescopes of eight new 6.0 < z < 6.5 quasars with z < 21.0. These quasars were pho…
A Study of Quasar Selection in the Dark Energy Survey Supernova fields
S. S. Tie, P. Martini, D. Mudd +75
We present a study of quasar selection using the DES supernova fields. We used a quasar catalog from an overlapping portion of the SDSS Stripe 82 region to quantify the completenes…
Discovery of a z=0.65 Post-Starburst BAL Quasar in the DES Supernova Fields
Dale Mudd, Paul Martini, Suk Sien Tie +55
We present the discovery of a z=0.65 low-ionization broad absorption line (LoBAL) quasar in a post-starburst galaxy in data from the Dark Energy Survey (DES) and spectroscopy from…
