Proposal Abstract

Only two AGN are known to emit gamma-rays above 300 GeV -- Mkn 421 and Mkn 501. The former is a weak EGRET source and the latter has not been detected by EGRET. The parsec-scale jet in Mkn 501 is almost orthogonal (on the plane of the sky) to the kiloparsec-scale jet, and there is some evidence that the same may be true for Mkn 421. We propose to make 5 GHz images of these two BL Lac objects during their atmospheric Cerenkov observing season to examine `orthogonal jet' models, and search for possible correlations between the VLBI structures and TeV activity.

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.
