PublicationThe quasar MBH-Mhost relation through cosmic time - II. Evidence for evolution from z = 3 to the present age
We study the dependence of the relation on the redshift up to z = 3 for a sample of 96 quasars, the host galaxy luminosities of which are known. Black hole...

PublicationThe radio luminosity function from the low-frequency 3CRR, 6CE and 7CRS complete samples
We measure the radio luminosity function (RLF) of steep-spectrum radio sources using three redshift surveys of flux-limited samples selected at low (151 and...

PublicationThe redshift and broad-band spectral energy distribution of NRAO 150
Context. NRAO 150 is one of the brightest radio and mm AGN sources in the northern sky, and is an interesting source to study extreme relativistic jet phenomena...

PublicationThe ROSAT UK medium sensitivity survey.
The authors present the first results on the optical identification of 89 ROSAT sources on the second Lockman hole. Because of the low Galactic H I column...
