Proposal Abstract

We have shown that OT081 possibly has the very large Doppler factor (delta) of 128\pm10 and the very large Lorentz factor (\Gamma) of 64\pm5. These values are the largest delta and \Gamma we have known to date, respectively. The Lorentz factor of 64 probably exceeds the terminal velocity achieved by photon pressure and the limit of Compton-drag. The systematic errors, however, are possible to be included in these values because the derived values strongly depend on the size of component. Our aim is to inspect the large Doppler factor of 128 and the large Lorentz factor of 64. We propose the dual-polarization VSOP observation for the accurate measurement of Doppler factor.

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 AO3 proposals were submitted in October 1999, 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.
