Proposal Abstract

We propose to monitor Centaurus A, the nearest active galaxy, extensively at 5 GHz and 1.6 GHz on several different time scales during early--mid 1999 when the \uv coverage is optimal. These observations will produce images of the sub-parsec jet components with a resolution 25 times better than images in our extensive 8.4 GHz monitoring campaign and 3 times better than our 22 GHz studies. The data will allow us to better understand the complex behavior of the sub-parsec jet flow, to test theoretical models for the differences between Fanaroff & Riley classes I and II, and to use jet structure to probe the environment of 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 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.
