Proposal Abstract

We propose to observe seven gamma-ray blazars with Space VLBI at 5 and 22 GHz. This is part of our effort to explore the relationship between gamma-ray emission and nonthermal emission at other wavebands. Proposed observations, combined with standalone VLBA observations at 15 and 43 GHz, will enable us to measure accurately the spectral index and size of the jet components, the synchrotron self-absorption frequency and flux density at this freqency. These properties are critical to the inverse Compton calculation. Together with observations with VLBA, MERLIN and VLA, they will also allow us to trace the jet from arcsecond scales to the innermost region of the core. With detection of helical jets with a few complete turns, we will be able to explore the binary black hole scenario, and model the jets geometrically or kinematically to constrain the jet angle to the line of sight.

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.
