Proposal Abstract

Despite their different classifications, 3C216 and 3C446 exhibit several striking similarities (e.g. CSS characteristics, superluminal motion, extreme misalignment of mas and the more extended structure, sudden as well as smooth curvature of the jets etc.) Questions remain as to the nature of the basic mechanism of the inner structural evolution concerned. VSOP space VLBI observations at 1.6, 5, and 22 GHz are requested to image these sources on the scales from 0.2 mas to 15 mas. Basic questions which we would like to clarify by these observations are: Is 3C446 a more distant "relative" of CSS sources? What are the similarities in the core-jet relation of these sources and what are the differences, particularly, close to the core? What are the spectral properties? Is there evidence of interaction with a dense interstellar medium on this scale, or can the curved jet structure be explained by precession?

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.
