Proposal Abstract
The archetypical quasar 3C 273 is an excellent candidate for studies
with VSOP. Our ongoing monitoring with VSOP has shown that the jet of
3C 273 is transversely resolved, and can be decomposed, for the first
time, into two distinct emitting components, possibly related to the
plasma instabilities in the jet. We propose here to continue VSOP
monitoring of 3C 273 at 5 GHz, and study in detail structural
evolution in the parsec--scale jet of this source. Our scientific
objectives are: (1) measuring the transverse jet profiles;
(2) measuring velocity gradients across the jet; (3) measuring
component variations closer to the core than possible from the ground
(where mm-VLBI imaging has not yet been able to produce detailed and
reliable images); and (4) high-dynamic range imaging of the jet structure
and polarization properties.
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.
