Proposal Abstract

NGC5793 is an edge-on spiral galaxy which is seen in absorption against a radio continuum source located near its nucleus. Also, known as one of the inflared luminous galaxies ,but no definite evidence for existence of AGN components inside the galaxy has ever been shown in any wave lengths. According to the observation at frequencies of radio and IRAS bands , the flux at radio 21cm continuum is too strong compared with that of IRAS wave bands. It indicates that the strong non-thermal emission mechanism in it and that its nucleus is hidden in the dusty molecular gas which is often seen in the Seyfert 2 type galaxies and inside that AGN must exist. We propose to detect a molecular ring around its nucleus using OH absorption line. And this unusual property of NGC5793 may lead to solve the unified theory between Quasars and Seyferts.

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.
