Proposal Abstract

We propose VSOP observations of the nearby powerful radio galaxy NGC 6251 at 1.6 and 5 GHz. In our previous VLBA (15 GHz) and VSOP (5 GHz) observations of NGC 6251, we discovered a new knot at 2 mas from the core and heavy absorption at the core. Therefore, our main purposes in the present proposal are; (1) to monitor the morphological evolution of the new knot, (2) to monitor the change of the wiggling pattern of the jet, and (3) to investigate the the continuum spectrum of the core and the jet, which will be highly useful in investigating the absorption processes.

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 AO3 proposals were submitted in October 1999, 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.
