Proposal Abstract
The Kellerman et al. 1998 2CM sample shows a remarkable
variety of radio sources,
but the most remarkable are those without extended structure.
Given the high angular resolution and dynamic range of the { 2 cm} sample,
and since the redshifts are known, the physical sizes must be smaller
than a few par-secs.
These sources should be extended unless the components are confined
and moving slowly (velocities < 0.01 c), or are young,
age < 100 years.
These observations at 6 cm with HALCA will better determine the angular size
of the sources, by searching for steep spectrum emission, typical of
jets, near the bright core. For the marginally resolved sources,
the spectral indices of the components will be determined.
These observations are also important for tests of the HALCA mission
performance.
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.
