Scattering from Dusty Outflows in Hot Dust-Obscured Galaxies with Blue Excess Emission
R. J. Assef, M. Stalevski, F. E. Bauer +15
(Context) Hot Dust-Obscured Galaxies (Hot DOGs) are a population of hyper-luminous quasars heavily obscured by dust and gas. While most have rest UV/optical SEDs dominated by their…
Hidden Monsters with SPHEREx I: A goldmine for heavily reddened quasars at cosmic noon
Matthew Stepney, Manda Banerji, Franz E. Bauer +2
Heavily reddened quasars (HRQs) are luminous, dust-obscured broad-line quasars thought to represent a short-lived phase of intense black hole growth and feedback. Previous studies…
The rest ultraviolet to infrared spectral energy distributions of heavily reddened quasars are "V-shaped" and hot-dust poor
Matthew Stepney, Manda Banerji, Shenli Tang +2
We present a rest-ultraviolet to infrared spectral energy distribution (SED) analysis of 63 heavily reddened quasars (HRQs) at redshifts z=0.7-2.7 and with dust extinctions E(B-V)=…
Evidence for universal gas depletion in a sample of 41 luminous Type 1 quasars at z 2
S. J. Molyneux, M. Banerji, M. J. Temple +9
We present ALMA CO observations of the molecular gas in a sample of 41 luminous unobscured quasars at z 2 from the Sloan Digital Sky Survey. 32 targets comprise the main sam…
A Big Red Dot: Scattered light, host galaxy signatures and multi-phase gas flows in a luminous, heavily reddened quasar at cosmic noon
Matthew Stepney, Manda Banerji, Shenli Tang +5
We present a deep X-Shooter rest-frame UV to optical spectral analysis of the heavily reddened quasar, ULASJ2315+043 at z=2.566, known to reside in a major-merger host galaxy. The…
A disc wind model for blueshifts in quasar broad emission lines
James H. Matthews, Jago Strong-Wright, Christian Knigge +7
Blueshifts - or, more accurately, blue asymmetries - in broad emission lines such as CIV 1550 are common in luminous quasars and correlate with fundamental properties such as Ed…
No redshift evolution in the rest-frame UV emission line properties of quasars from z=1.5 to z=4.0
Matthew Stepney, Manda Banerji, Paul C. Hewett +4
We analyse the rest-frame UV spectra of 2,531 high-redshift (3.5<z<4.0) quasars from the Sloan Digital Sky Survey DR16Q catalogue. In combination with previous work, we study the r…
Testing AGN outflow and accretion models with CIV and HeII emission line demographics in z=2 quasars
Matthew J. Temple, James H. Matthews, Paul C. Hewett +6
Using 190,000 spectra from the seventeenth data release of the Sloan Digital Sky Survey, we investigate the ultraviolet emission line properties in z=2 quasars. Specifically, we qu…
