Proposal Abstract

We propose VSOP imaging of the quasar 3C 345 (3 epochs at 18 cm, 3 at 6 cm, and 8 at 1.3 cm). Building on our ongoing ground monitoring campaigns, this project will enable us to study this archetype of a high-luminosity, core-dominated, superluminal source with unprecedented angular resolution, and to constrain models for the physical properties of parsec-scale radio jets. Our observational objectives are: (1) Measuring the epoch of occurrence, flux and size evolution, trajectories, velocities, and accelerations of superluminally moving regions; (2) Superior dynamic-range/resolution imaging of the complex jet brightness structure (total and polarized intensity and spectral index distribution); (3) Measuring the relative location and size (or an upper limit thereof) of the thus far unresolved central region; (4) Imaging the linear polarization intensity and determining the magnetic field strength and its spatial distribution along the jet.

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.
