Gemini Near Infrared SpectrographDistant Quasar Survey: the Chandra View
Andrea Marlar, Ohad Shemmer, Michael S. Brotherton +5
We present Chandra observations of 63 sources from the Gemini Near Infrared SpectrographDistant Quasar Survey (GNIRS-DQS) of which 54 were targeted by snapshot observations in C…
Exploring the Spectral Energy Distributions of Luminous Broad Absorption Line Quasars at High Redshift
Harum Ahmed, Sarah C. Gallagher, Ohad Shemmer +4
We present the multiwavelength spectral energy distributions (SEDs) for 65 luminous broad absorption line (BAL) quasars with redshifts from the Gemi…
Rest-Frame Optical Spectroscopy of Ten z 2 Weak Emission-Line Quasars
Ying Chen, Bin Luo, W. N. Brandt +7
We present near-infrared spectroscopy of ten weak emission-line quasars (WLQs) at redshifts of , obtained with the Palomar 200-inch Hale Telescope. WLQs are an exceptional…
Gemini Near Infrared Spectrograph -- Distant Quasar Survey: Rest-Frame Ultraviolet-Optical Spectral Properties of Broad Absorption Line Quasars
Harum Ahmed, Ohad Shemmer, Brandon Matthews +12
We present the rest-frame ultraviolet-optical spectral properties of 65 broad absorption line (BAL) quasars from the Gemini Near Infrared Spectrograph-Distant Quasar Survey (GNIRS-…
