Proposal Abstract

VSOP polarization images at 5 GHz are now available for four BL Lac objects: 0735+178, OJ287, 1334--127, and 1803+784. Each of these observations has led to new and unexpected results that have furthered our understanding of the compact radio structure of these sources. We propose here 5 GHz VSOP polarization observations of an additional 13 strongly polarized BL Lacertae objects. The resulting images would provide valuable new information about the physical origin of the transverse magnetic fields that are characteristic of the VLBI jets of these objects, the highly polarized knots that previous 5 GHz VSOP polarization observations have shown to dominate the ground-based core polarization, and the weaker intrinsic polarization of the 5-GHz cores.

The full Cover Sheets (compressed post-script, typically 50kbytes) can be retrieved. Note that some 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 AO4 proposals were submitted in October 2000, and information such as affiliations and contact details has changed for some proposers since that time.
