Proposal Abstract
We propose VSOP imaging observations of 3C 120 at both 1.6 GHz and
5 GHz. The nearness of this galaxy (z=0.033) allows high-resolution
imaging closer to the central engine than
is possible in other superluminal sources;
the resolution of VSOP at 5 GHz will be close to 0.1 pc, well within
the galaxy's Broad Line Region. A large ground array is requested
to enable high-fidelity imaging of this equatorial source.
This will permit higher resolution studies of complex structures that
seem to be present within the smooth outer envelope of the jet, as indicated
by VLBA imaging. Separately, we
will request contemporaneous MERLIN observations to extend the range
of u-v spacings, providing the opportunity to study the jet structures
over four orders of magnitude in size scale.
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 AO1 proposals were submitted in November 1995, 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.
