Proposal Abstract

We propose to observe the compact source 4C 39.25 with the VLBA and VSOP for two epochs at 1.3 cm and one epoch at 6 cm. We intend to monitor the `collision' of the superluminally moving component b with the stationary component a, taking advantage of the high angular resolution provided by VSOP at centimetre wavelengths, and to understand the reasons of the dramatic increase in total flux density of the radio source. Combination of the results from these experiments with our ongoing VLBI monitoring with earth-based arrays at cm- and mm-wavelengths will give us the necessary structural- and spectral-information required to test the physical jet models we have developped for this source.

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.
