Proposal Abstract

We propose to observe the gravitationally lensed, radio loud BL Lac B0218+357, to determine the physical parameters of this lensing system such as relative magnification factors and intrinsic source structures. VSOP observations at 1.6 and 5 GHz will allow us to image the milliarcsecond-scale jet components with high resolution at wavelengths where they are bright. Detection of such features will provide valuable new constraints on the mass distribution and potential shape of the lensing galaxy.

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.
