Radio Loud Quasars at High Redshift

1998
We present results from an observational investigation into the evolution of the luminosity function of flat spectrum radio loud quasars based on a new survey for radio loud quasars with z>3. Rather than carry out an indiscriminate redshift campaign on all the radio sources in our sample, we use optical colours to preselect red stellar identifications ...
