AllBRICQS: the All-sky BRIght, Complete Quasar Survey - Quasar Selection and Final Southern GRP<16 Sample
Abstract
We describe the final quasar sample from the Southern part of the All-sky BRIght, Complete Quasar Survey (AllBRICQS), which aimed to discover the remaining optically bright quasars using data from Gaia and WISE. We discuss our final selection and present a further 119 quasars in the redshift range z=[0.03;4.35]. This brings the sample of spectroscopically confirmed quasars with GRP<16 and z>0.1 at Dec<+20∘ and Galactic latitude |b|>10∘ to 745 objects. The spectra from the ANU 2.3m telescope at Siding Spring Observatory cover a wavelength range from 360 to 950 nm with R∼3000. For redshifts of z>0.12, we expect the sample to be complete at GRP<16, a regime that is usually avoided by large spectroscopic surveys due to detector saturation. We note that at least one strongly lensed quasar has escaped our selection.
