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…
The intrinsic X-ray luminosity distribution of an optically-selected SDSS quasar population
Amy L. Rankine, James Aird, Angel Ruiz +1
In active galactic nuclei, the relationship between UV and X-ray luminosity is well studied (often characterised by ) but often with heterogeneous samples. We have par…
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…
