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…
Spectroscopic confirmation of dual and offset quasars from the Subaru HSC-SSP program
Shenli Tang, John Silverman, Xavier Prochaska +4
We present a spectroscopic follow-up program targeting closely-separated dual quasar candidates selected from imaging of SDSS quasars with the Subaru Hyper Suprime-Cam Subaru Strat…
Euclid Quick Data Release (Q1): Euclid spectroscopy of quasars. 1. Identification and redshift determination of 3500 bright quasars
Euclid Collaboration, Y. Fu, R. Bouwens +354
The slitless spectroscopy mode of the NISP onboard Euclid has enabled efficient spectroscopy of objects within a large FoV. We present a large and homogeneous sample of bright quas…
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)=…
NASIM: Revealing the low surface brightness Universe from legacy VISTA data
Elham Saremi, Ignacio Trujillo, Mohammad Akhlaghi +5
Near-infrared imaging is a powerful technique in observational astronomy, but the bright background, primarily from the EarthÅ atmosphere, makes the detection of faint features pa…
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…
