Proposal Abstract

We propose VSOP observations of the quasar 3C273 in order to extend our ground-based VLBI studies of the jet to higher resolution. Global VLBI observations at 18cm have traced the jet out to 200 pc and the superluminal motion continues to the outermost components. Higher resolution observations will allow us to study the complex structure of the jet in detail and determine whether the apparent velocities change along the jet. VSOP observations at 18cm offer the ideal combination of resolution and sensitivity to the extended steep-spectrum jet emission to carry out this study. VSOP observations made in December have yielded good quality data and preliminary images trace the jet out to 80 mas. In order to trace the motions of the jet features we request one further observation in AO2.

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.
