Can X-ray Observations Improve Optical-UV-based Accretion-Rate Estimates for Quasars?
Andrea Marlar, Ohad Shemmer, Michael S. Brotherton +2
Current estimates of the normalized accretion rates of quasars (L/L_Edd), rely on measuring the velocity widths of broad optical-UV emission lines (e.g., H and Mg II $\lambda280…
Placing High-Redshift Quasars in Perspective: a Catalog of Spectroscopic Properties from the Gemini Near Infrared Spectrograph -- Distant Quasar Survey
Brandon M. Matthews, Ohad Shemmer, Cooper Dix +15
We present spectroscopic measurements for 226 sources from the Gemini Near Infrared Spectrograph - Distant Quasar Survey (GNIRS-DQS). Being the largest uniform, homogeneous survey…
Prescriptions for Correcting Ultraviolet-Based Redshifts for Luminous Quasars at High Redshift
Cooper Dix, Ohad Shemmer, Michael S. Brotherton +3
High-redshift quasars typically have their redshift determined from rest-frame ultraviolet (UV) emission lines. However, these lines, and more specifically the prominent C IV $λ154…
