A Multi-Colour Survey For High-Redshift Quasars
We describe how the application of techniques which utilise all the information contained in multi-colour surveys of stellar-like objects can be employed to detect quasars over an extended redshift range. The method is particularly effective for the identification of quasars with redshifts z>2.2 where the application of the ultra-violet excess criterion breaks down. Spectroscopy of a small sample of objects from the first survey field has resulted in the detection of two new faint quasars withdoi:10.1007/978-94-009-3853-3_73 fatcat:m4pcnrqtmncr5la7hdnzruqtxi
