AllBRICQS: the All-sky BRIght, Complete Quasar Survey
Christopher A. Onken, Christian Wolf, Wei Jeat Hon +3
We describe the first results from the All-sky BRIght, Complete Quasar Survey (AllBRICQS), which aims to discover the last remaining optically bright quasars. We present 156 spectr…
Discovery of the most luminous quasar of the last 9 Gyr
Christopher A. Onken, Samuel Lai, Christian Wolf +8
We report the discovery of a bright (g = 14.5 mag (AB), K = 11.9 mag (Vega)) quasar at redshift z = 0.83 -- the optically brightest (unbeamed) quasar at z > 0.4. SMSS J114447.77-43…
Chemical Abundance of z~6 Quasar Broad-Line Regions in the XQR-30 Sample
Samuel Lai, Fuyan Bian, Christopher A. Onken +17
The elemental abundances in the broad-line regions of high-redshift quasars trace the chemical evolution in the nuclear regions of massive galaxies in the early universe. In this w…
