Proposal Abstract

We propose to image in both total intensity and linear polarization the four brightest and best studied quasars 3C 273, 3C 279, 3C 345, and 3C 454.3. Each quasar will be observed twice within the observing windows at each of three frequencies, to look for rapid variations, together with quasi-simultaneous matched resolution observations with the VLBA alone. These observations will provide images of unmatched resolution and uv plane coverage, and will enable us to explore the innermost parts of relativistic jets. We shall obtain spectra and sizes of the youngest features in the jets, explore the development of ordered magnetic fields through shocks and boundary layer interactions, and search for Faraday rotation and depolarization in the dense ambient gas surrounding the central engine.

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.
