Proposal Abstract

We propose VSOP plus VLBA (plus Effelsberg) observations at 5 GHz to make Phase 1 maps of the relatively strong nuclei in four double-lobed extragalactic radio sources: the lobe-dominated quasars 3C207 and 3C245 and the FRII radio galaxies 3C109 and 3C133. The superior beam size and shape as compared to ground-based VLBI will enable us to probe details of the exceedingly compact (<0.5 mas) structures known to exist in these objects. This will immediately permit tests of jet alignment and bending and later, with second-epoch Phase 2 maps, allow searches for superluminal motion. These investigations of compact morphology, jet curvature, and parsec-scale jet speeds will be of great value in testing AGN unification scenarios.

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 AO1 proposals were submitted in November 1995, 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.
