Proposal Abstract

We propose a monitoring observation of Cen A, the nearest Active Galactic Nuclei. The angular resolution of 0.1mas at 22GHz corresponds to a linear scale of only 2 light-days which is expected size of 15R_G of 10^9M_ sun supermassive black hole. This observation make it possible to see a reletivistic region. Some proposed theoretical models of AGN jet formation predict different shapes of the jets and different acceleration of jet components. The monitoring can resolve the accelerating region and distinguish these theoretical models. Therefore the Cen A monitoring observation is one of the most promising observations of all AGN study by VSOP. Since the proposed project is in-line with one of the goals of the Key Science Program, we would like to suggest to it is in a part of the VSOP KSP.

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.
