Proposal Abstract

J1922+155 is a compact radio source along with the galactic plane. A short glance of the Palomar Sky Survey print shows no corresponding object. We have observed the total flux density, and found that the radio spectrum is inverted between 2 and 15 GHz. This suggests that the object is a core-dominant extragalactic source. The VLBA Calibrator Survey shows that the source has a morphology with a slightly elongated component and an extended lobe within a few tens of mas. A powerful way to reveal the nature of the object is to observe with a highly spatial resolution at a low frequency. This kind of observations has an ability to resolve the central component into a core + jets and to detect optically thick radiation, where the source is non-thermal. We then propose VSOP observations at 5 GHz for the 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 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.
