Revisiting the X-ray-to-UV relation of Quasars in the era of all-sky surveys
Maria Chira, Antonis Georgakakis, Angel Ruiz +8
The X-ray--to--UV relation of active galactic nuclei (AGNs), commonly parametrized via the monochromatic luminosities at and , reflects the energetic i…
Exploring the quasar disc-wind-jet connection with LoTSS and SDSS
Charlotte L. Jackson, James H. Matthews, Imogen H. Whittam +4
We investigate the relationship between disc winds, radio jets, accretion rates and black hole masses of a sample of 100k quasars at z 2. Combining spectra from the…
An Extremely-High Velocity Outflow in SMSS J2157-3602, the most luminous quasar in the first 1.3 Gyr
Giustina Vietri, Paola Rodriguez Hidalgo, Amy Rankine +16
We report the discovery of an extremely high-velocity outflow (EHVO) in the most luminous ( 2.29 10 erg/s) QSO, SMSS J2157-3602, at z=4.692. Comb…
X-ray selected broad absorption line quasars in SDSS-V: BALs and non-BALs span the same range of X-ray properties
Pranavi Hiremath, Amy L. Rankine, James Aird +10
Broad absorption line (BAL) quasars are often considered X-ray weak relative to their optical/UV luminosity, whether intrinsically (i.e., the coronal emission is fainter) or due to…
The Nineteenth Data Release of the Sloan Digital Sky Survey
SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210
Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy
Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts +217
The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the s…
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…
