Proposal Abstract

We propose to continue our VSOP monitoring of 3C279 at 1.6 and 5 GHz with additional epochs in June 2000 and Jan-Feb 2001. The bright component at 3 mas has recently undergone an acceleration and polarization change; further monitoring of this component may allow the 3-dimensional trajectory of the jet to be mapped. We also propose to make the June 2000 epoch a coordinated multiwavelength observation with the ASCA X-ray satellite and the VLBA at higher frequencies. Spectral index maps made from matched resolution VSOP and VLBA observations show great promise; this matched resolution will help significantly in fitting component spectra and in determining the inverse Compton Doppler factor and the dominant X-ray emitting component in 3C279. Homogeneous and inhomogeneous SSC and external Compton emission models will be tested.

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.
