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 ...

Radio Loud Broad Absorption Line Quasars

2009
This thesis is concerned with Broad Absorption Line Quasars (BAL QSOs). At the moment it is not clear how many quasars host outflows and why these can only be seen in a fraction of the quasar population. The most popular hypotheses proposed to explain this mainly differ in the role given to orientation.
