Proposal Abstract

One of the most valuable results of the VSOP mission will be an uninterrupted series of images for a few sources over the entire VSOP mission lifetime. Such continuous monitoring is only possible over a small region of the sky. We propose such a unbroken monitoring campaign (with the possible exception of the two months beginning in October 1997) at both 5 GHz and 22 GHz on the superluminal quasar 1928+738. We hope to confirm or reject the hypothesis that the observed wiggle in the jet is caused by the orbital motion of a massive binary black hole system as has been proposed to be the cause of helical jet motion seen in this and other core-dominated radio sources.

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.
