Connection between Emission and Absorption Outflows through the Study of Quasars with Extremely-High Velocity Outflows
Paola Rodríguez Hidalgo, Amy Rankine
A recently-discovered class of outflows, extremely high-velocity outflows (EHVOs), may be key to understanding feedback processes as it is likely the most powerful in terms of mass…
A Novel Test of Quasar Orientation
Gordon T. Richards, Richard M. Plotkin, Paul C. Hewett +4
The orientation of the disk of material accreting onto supermassive black holes that power quasars is one of most important quantities that are needed to understand quasars -- both…
High-ionization emission line ratios from quasar broad line regions: metallicity or density?
Matthew J. Temple, Gary J. Ferland, Amy L. Rankine +2
The flux ratios of high-ionization lines are commonly assumed to indicate the metallicity of the broad emission line region in luminous quasars. When accounting for the variation i…
Placing LOFAR-detected quasars in CIV emission space: implications for winds, jets and star formation
Amy L. Rankine, James H. Matthews, Paul C. Hewett +3
We present an investigation of the low-frequency radio and ultraviolet properties of a sample of 10,500 quasars from the Sloan Digital Sky Survey Data Release 14, observed…
Exploring the link between C IV outflow kinematics and sublimation-temperature dust in quasars
Matthew J. Temple, Manda Banerji, Paul C. Hewett +2
Using data from SDSS, UKIDSS and WISE, we investigate the properties of the high-frequency cutoff to the infrared emission in 5000 carefully selected luminous ($L_{bol} \si…
Characterizing Quasar CIV Emission-line Measurements from Time-resolved Spectroscopy
A. B. Rivera, G. T. Richards, P. C. Hewett +1
We use multi-epoch quasar spectroscopy to determine how accurately single-epoch spectroscopy can locate quasars in emission-line parameter space in order to inform investigations w…
