Proposal Abstract

We propose two epochs of 1.6 and 5 GHz observations of the compact, flat spectrum QSO NRAO 530. These observations will allow us to address the emission mechanisms in this unusual source. Our high frequency monitoring, which we will continue to match VSOP observations, has shown frequency independent structure from 86 to 15 GHz. If this trend continues to decimeter wavelengths we expect to see a significant violation of the inverse Compton limit. The specific structure will allow us to address the nature of the flat spectrum in this source: Is it the superposition of multiple distinct components or is it from a single component with a self-similar geometry? The expected range of sizes, 100 to 1000 micro-arcsec, is well-matched to VSOP resolution at these frequencies. Two epochs of observation compensate for the effects of variability in this active source.

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.
