Proposal Abstract

Recently there has been proposed a unified scheme that parent galaxies of BL Lac objects are FR I radio galaxies and those of quasars are FR II radio galaxies. And evidence is growing that FR I galaxies have relativistic jets in their innermost regions and they are decelerated at radii of parsecs' scale. According to this unified scheme, it is expected that relativistic jets and their deceleration at such small radii are discovered also in BL Lac objects. We shall make monitoring observations of BL Lac objects with high angular resolutions by using the VSOP over several months in order to detect the small-scale relativistic jets, to catch the deceleration, and to test the unified scheme.

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.
