Christopher A. Onken, Christian Wolf, Wei Jeat Hon, Samuel Lai,, Patrick Tisserand, and Rachel Webster

TL;DR
The AllBRICQS survey has identified 156 bright quasars across the sky, including many new discoveries, significantly expanding the catalog of optically bright quasars for future astrophysical research.
Contribution
This work presents the first results from a new all-sky survey combining Gaia and WISE data to discover bright quasars, achieving high completeness and purity in identification.
Findings
156 spectroscopically confirmed quasars, 140 newly identified
High completeness (~96%) and purity (~96%) in quasar selection
Discovery of extremely luminous high-redshift quasar J0529-4351
Abstract
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 spectroscopically confirmed quasars (140 newly identified) having |b|>10deg. 152 of the quasars have Gaia DR3 magnitudes brighter than B_P=16.5 or R_P=16 mag, while four are slightly fainter. The quasars span a redshift range of z=0.07-3.93. In particular, we highlight the properties of J0529-4351 at z=3.93, which, if unlensed, is one of the most intrinsically luminous quasars in the Universe. The AllBRICQS sources have been selected by combining data from the Gaia and WISE all-sky satellite missions, and we successfully identify quasars not flagged as candidates by Gaia Data Release 3. We expect the completeness to be approximately 96% within our magnitude and latitude limits, while the preliminary results indicate…
