The probabilistic random forest applied to the QUBRICS survey: improving the selection of high-redshift quasars with synthetic data
Francesco Guarneri, Giorgio Calderone, Stefano Cristiani +10
Several recent works have focused on the search for bright, high-z quasars (QSOs) in the South. Among them, the QUasars as BRIght beacons for Cosmology in the Southern hemisphere (…
The Probabilistic Random Forest applied to the selection of quasar candidates in the QUBRICS Survey
Francesco Guarneri, Giorgio Calderone, Stefano Cristiani +5
The number of known, bright (), high-redshift () QSOs in the Southern Hemisphere is considerably lower than the corresponding number in the Northern Hemisphere due to…
The Luminosity Function of bright QSOs at z~4 and implications for the cosmic ionizing background
K. Boutsia, A. Grazian, F. Fontanot +8
Based on results by recent surveys, the number of bright quasars at redshifts z>3 is being constantly revised upwards. Current consensus is that at bright magnitudes ($M_{1450}\le…
The spectroscopic follow-up of the QUBRICS bright quasar survey
K. Boutsia, A. Grazian, G. Calderone +11
We present the results of the spectroscopic follow up of the QUBRICS survey. The selection method is based on a machine learning approach applied to photometric catalogs, covering…
