2.6. Ultraviolet Selection

While it has long been possible to select high-redshift objects in the rest-frame UV - and this is often the main path to "optical" selection of quasars - until 2003 there has been no large-scale survey in the UV for active galaxies. This will be remedied with the recent successful launch of the Galaxy Evolution Explorer (GALEX) satellite. To date, there has not been a rest-frame UV survey for AGN covering a reasonable solid angle with reasonable sensitivity.
