Proposal Abstract

We propose VSOP polarization sensitive observations of the FRI radio galaxy NGC 315 at 18 cm wavelength to augment existing ground based VLBI polarimetric observations with comparable resolution at 6 cm. This will allow separating the effects of magnetic field orientation, optical depth, and Faraday rotation on much finer size scales than is possible from ground based observations alone. The particular problem we would like to address is the apparent lack of motion observed in the source which might be expected in the beamed emission model on the basis of the asymmetries on the jets at both parsec and kiloparsec scales. Multifrequency images of polarized emission will help in the comparison of the observations with the predictions of various models. Moreover we will obtain a high resolution spectral index map. It will show the regions where particle acceleration is present and will help in understanding the nature of knots.

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.
