Proposal Abstract
We propose to search for structural changes in images of the extremely compact
core-jet of the nearby spiral galaxy M81 with a linear resolution of up to
1,000 AU. Our goals are to (1) search for components in the bent and structurally
variable jet recently found with ground-based VLBI albeit with marginal
linear resolution at the source; (2) measure the components' proper motion;
(3) address the question of jet fading in the context of jet motion; and
(4) contribute to the discussion of
a continuum of AGN activity with radio luminosities ranging from that of
SgrA^{*} to that of M81 and those of powerful radio galaxies and quasars.
We propose three experiments at 1.6 GHz and three experiments at 5 GHz, each
one between a few days and a few weeks apart so that component speeds of about c
could be detected.
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.
