Proposal Abstract

3C 84(z=0.018) is one of the near-by sources among active galactic nuclei (AGNs). We have observed this source twice with VSOP, and once with VLBA. Double-ridgeline structure has been shown by the previous VSOP observations. We conclude that this structure must be a jetstream and a back. We also found that the jet has a wiggled structure. We think that this structure could be due to Kelvin-Helmholtz instability between jet and back flow. The jets motion and spectral index distribution will give us the clues to solve this wiggled structure.

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.
