QUBRICS: Selecting bright QSOs at high-z with Machine Learning techniques.

by Dr Giorgio Calderone (INAF- OATS)

Tuesday 3 Jun 2025, 11:30 → 12:30 Europe/Rome

Sala Jappelli (Osservatorio astronomico di Padova)

The ``QUasars as BRIght beacons for Cosmology in the Southern hemisphere'' (QUBRICS) project aims to identify the brightest and high-redshift QSOs in currently available surveys using machine-learning methods. In the talk I will illustrate the adopted methods focusing on CCA (Canonical Correlation Analysis) and XGBoost, as well as presenting the reverse-selection heuristic aimed at improving selection completeness.  Finally, I will show the QUBRICS results obtained so far.
