JHK Imaging of QSO Hosts and Companionssystematic offsets at z≤0.3. The QSO luminosity profiles are complex and reveal some of their tidal disturbance and star-formation history. At high redshift, the models match well, and indicate compact groups of galaxies with young populations.

Adaptive Optics Observations of Quasar Hostss will complement space based observation. Here we present first results from a pilot project to study quasar hosts with adaptive optics, and discuss the need for better defined samples of distant AGN and galaxies suitable for adaptive optics study.

Remarks on the Extended Light in Quasarsear phenomena. Some comments are made about the importance of the rest-frame waveband and the likely appearance of ‘pseudo-host’ galaxies resulting from locally scattered quasar light and spatially-extended emission line regions.

The Unified Schemes and Radio Polarization Studiesar objects being seen with different angles of inclination to the observer. The orientation dependence arises due to bulk relativistic motion of the non-thermal jets squirting out from the active nucleus, and anisotropic distribution of circumnuclear material, which is possibly in the form of a toru
