Proposal Abstract

The study of the parsec-scale morphology and kinematics of quasars is central to the understanding of extragalactic radio source jet physics, and the classification of various types of objects. In the "unified schemes" the properties of sources should depend crucially upon the angle of a relativistically moving plasma with respect to the line of sight. Core-dominated sources should show properties corresponding to an axis nearly pointing at the observer - superluminal motion, exaggeration of small bends, and strong and variable cores. In contrast, in lobe- dominated quasars these properties should be weak or absent. We wish to make SECOND EPOCH VSOP OBSERVATIONS of our small sample of LOBE-DOMINATED QUASARS, to compare the sub-mas structures and component velocities with those of the stronger core-dominated quasars. Our sources are at high declinations, and are thus ideal for efficient use of VSOP-GRT time.

The full Cover Sheets (compressed post-script, typically 50kbytes) can be retrieved. Note that many proposals were reduced in extent by the Scientific Review Committee (e.g. by reducing the number of experiments), however the Cover Sheets contain the full proposal as submitted. Also note that AO2 proposals were submitted in May 1998, and information such as affiliations and contact details has changed for some proposers since that time. The Cover Sheets (and the details on this page, which were derived from the Cover Sheets) may therefore have changed.
