Radio Quasars in the Cosmic Dawn: A Spectroscopic Sample from the DESI Survey

Anniek J. Gloudemans, Jinyi Yang, David M. Alexander +55

We present the largest statistical spectroscopic sample of radio quasars at 4.7<z<6.7 to date. These have been selected from a dedicated Dark Energy Survey Instrument (DESI) target…

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-…

A striking relationship between dust extinction and radio detection in DESI QSOs: evidence for a dusty blow-out phase in red QSOs

V. A. Fawcett, D. M. Alexander, A. Brodzeller +39

We present the first eight months of data from our secondary target program within the ongoing Dark Energy Spectroscopic Instrument (DESI) survey. Our program uses a mid-infrared a…

Siena Galaxy Atlas 2020

John Moustakas, Dustin Lang, Arjun Dey +8

We present the 2020 version of the Siena Galaxy Atlas (SGA-2020), a multi-wavelength optical and infrared imaging atlas of 383,620 nearby galaxies. The SGA-2020 uses optical …

Detecting and Characterizing Mg II absorption in DESI Survey Validation Quasar Spectra

Lucas Napolitano, Agnesh Pandey, Adam D. Myers +33

We present findings of the detection of Magnesium II (Mg II, λ = 2796, 2803 Å) absorbers from the early data release of the Dark Energy Spectroscopic Instrument (DESI). DESI is pro…

Gemini Near Infrared Spectrograph -- Distant Quasar Survey: Augmented Spectroscopic Catalog and a Prescription for Correcting UV-Based Quasar Redshifts

Brandon M. Matthews, Cooper Dix, Ohad Shemmer +13

Quasars at most often have redshifts measured from rest-frame ultraviolet emission lines. One of the most common such lines, C IV , shows blueshifts up to ${…
