Proposal Abstract

We propose single-epoch polarization observations of the quasar 1055+018 at 1.6 and 5 GHz. Global VLBI observations at 1.7 GHz indicate that the millisecond-scale structure is roughly perpendicular to the arcsecond-scale structure mapped by VLA observations (they are offset by 60--70 degrees). In addition, the source is extremely compact and substantially polarized. The proposed HALCA measurements would make it possible to study the behavior of the position angle of the jet structure as it extends from the VLBI core to arcsecond scales. The availability of linear polarization measurements will provide additional information about the magnetic field geometry along the apparently curved jet.

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.
