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 z ≳ 1 most often have redshifts measured from rest-frame ultraviolet emission lines. One of the most common such lines, C IV λ1549, shows blueshifts up to ${…

Shedding New Light on Weak Emission-Line Quasars in the CIV​-Hβ Parameter Space

Trung Ha, Cooper Dix, Brandon M. Matthews +20

Weak emission-line quasars (WLQs) are a subset of Type 1 quasars that exhibit extremely weak Lyα+N V λ1240 and/or C IV λ1549 emission lines. We investigate the relationship b…

Multi-phase gas interactions on subarcsec scales in the shocked IGM of Stephan's Quintet with JWST and ALMA

P. N. Appleton, P. Guillard, B. Emonts +12

We combine JWST and HST imaging with ALMA~CO(2-1) spectroscopy to study the highly turbulent multi-phase intergalactic medium (IGM) in Stephan's Quintet on 25-150 pc scales. Previo…
