Proposal Abstract
We propose to continue our investigations of the center of M81 which we recently
found to consist of a stationary core with a compact one-sided jittery jet. Together
with Cen A, M81 is the nearest galaxy with an AGN and permits studies with a
resolution at 6cm of 1,000 AU. Our goal is to focus on the jet's structure and variability.
Taking advantage of the exceptionally good u-v coverage, also perpendicular to the jet axis,
around February 2000, we propose to (1) measure the width of the jet and (2)
monitor recently discovered ~20\deg changes of the jet direction. We also plan to
extend our previous program
of (3) identifying components, (4) measuring their speeds which were inferred to be >0.25c,
and (5) contributing to the discussion of a continuum of AGN activity ranging from that of
the mostly obscured SgrA^* via that of M81 to that of powerful radio galaxies and quasars.
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.
