Correlations between O VI Absorbers and Galaxies at Low Redshift
Rajib Ganguly, Renyue Cen, Taotao Fang +1
We investigate the relationship between galaxies and metal-line absorption systems in a large-scale cosmological simulation with galaxy formation. Our detailed treatment of metal e…
Outflows and the Physical Properties of Quasars
Rajib Ganguly, Michael S. Brotherton, Sabrina Cales +3
We have investigated a sample of 5088 quasars from the Sloan Digital Sky Survey Second Data Release in order to determine how the frequency and properties of broad absorptions line…
A Census of Intrinsic Narrow Absorption Lines in the Spectra of Quasars at z=2-4
T. Misawa, J. C. Charlton, M. Eracleous +5
We use Keck/HIRES spectra of 37 optically bright quasars at z=2-4 to study narrow absorption lines that are intrinsic to the quasars (intrinsic NALs, produced in gas that is physic…
Probing Quasar Outflows with Intrinsic Narrow Absorption Lines
T. Misawa, M. Eracleous, J. C. Charlton +5
We present statistical and monitoring results of narrow absorption lines that are physically related to quasars (i.e., intrinsic NALs). We use Keck/HIRES spectra of 37 optically br…
Hubble Space Telescope Ultraviolet Spectroscopy of Fourteen Low-Redshift Quasars
Rajib Ganguly, Michael S. Brotherton, Nahum Arav +35
We present low-resolution ultraviolet spectra of 14 low redshift (z<0.8) quasars observed with HST/STIS as part of a Snap project to understand the relationship between quasar outf…
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…
