ReveaLLAGN 1: JWST Emission-Line Spectra Reveal Low-Luminosity AGN with UV-Deficient SEDs and Warm Molecular Gas
Kameron Goold, Anil Seth, Mallory Molina +20
We present near- and mid-infrared spectra of eight Low-Luminosity Active Galactic Nuclei (LLAGN), spanning nearly four orders of magnitude in black hole mass and Eddington ratio, o…
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-…
Radio Scrutiny of the X-ray-Weak Tail of Low-Mass Active Galactic Nuclei: A Novel Signature of High-Eddington Accretion?
Jeremiah D. Paul, Richard M. Plotkin, W. N. Brandt +6
The supermassive black holes () that power luminous active galactic nuclei (AGNs), i.e., quasars, generally show a correlation between t…
ReveaLLAGN 0: First Look at JWST MIRI data of Sombrero and NGC 1052
K. Goold, A. Seth, M. Molina +28
We present the first results from the Revealing Low-Luminosity Active Galactic Nuclei (ReveaLLAGN) survey, a JWST survey of seven nearby LLAGN. We focus on two observations with th…
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 ${…
Shedding New Light on Weak Emission-Line Quasars in the C-H 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 LyN V 1240 and/or C IV 1549 emission lines. We investigate the relationship b…
