VizieR Online Data Catalog: Bright QSOs in Southern Hemisphere (QUBRICS) (Calderone+, 2019)

We have carried out extensive spectroscopy observations at the Las Campanas Observatory and at the ESO-NTT telescope at La Silla. The results of these observations build up the QUBRICS (QUasar BRIllanti per la Cosmologia nell'emisfero Sud) survey.

The first pilot study was carried out at the Magellan telescopes in 2018 using LDSS-3 (Clay Telescope; 4000-10000Å and R~800) and IMACS (Baade Telescope). In 2019 February we were awarded 2 nights at the du Pont telescope to validate the optimized criteria, and we observed several new candidates with the Wide Field CCD (WFCCD) blue grism that covers a wavelength range between 3700-8000Å.

The NTT spectroscopic campaign has been carried out during the ESO observing period P103 under the proposal 0103.A-0746 (PI. A. Grazian). Three nights of spectroscopy have been executed during 2019 April 27-30. The EFOSC2 instrument was used, equipped with the grism #13 (~3700-9300Å).

Finally, in 2019 June we performed a few exposures at the Italian Telescopio Nazionale Galileo (TNG; operated on the island of La Palma) using the Low Resolution Spectrograph (Dolores) with the LR-B grism (resolution ~600).
