PublicationThe optical variability of 3C 345
B-magnitudes have been compiled from the literature for 3C 345, covering a period from 1965 to 1980, 905 values in all. Since the last major study of the light...

PublicationThe Peculiar Optical Spectrum of 4C+22.25: Imprint of a Massive Black Hole Binary?
We report the discovery of peculiar features in the optical spectrum of 4C+22.25, a flat spectrum radio quasar at z = 0.4183 observed in the Sloan Digital Sky...

PublicationThe Properties of Quasar Hosts at the Peak of the Quasar Activity
We present near-infrared imaging obtained with ESO VLT/ISAAC of a sample of 16 low luminosity radio-quiet quasars (RQQs) at the epoch around the peak of the...

PublicationThe quasar fraction in low-frequency-selected complete samples and implications for unified schemes
Low-frequency radio surveys are ideal for selecting orientation-independent samples of extragalactic sources because the sample members are selected by virtue...
