19 Sep 2022 | | 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 116 quasars (105 newly identified) having |b| > 10deg and
Gaia magnitudes brighter than B_P =16.5 or R_P =16 mag (plus another four at
slightly fainter magnitudes), which span a redshift range of z = 0.07 - 2.45.
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 a selection purity of approximately 97%. The
optical spectroscopy used for source classification will also enable detailed
quasar characterisation, including black hole mass measurements and
identification of foreground absorption systems. The AllBRICQS sources will
greatly enhance the number of quasars available for high-signal-to-noise
follow-up with present and future facilities. | | Source: | arXiv, 2209.09342 | | Services: | Forum | Review | PDF | Favorites | |
