Proposal Abstract

We propose to observe four EGRET blazars (0202+149, 1156+295, 1606+106, and 1611+343) that have been studied using geodetic VLBI data from the Washington VLBI Correlator's database (Piner & Kingham 1997a, 1997b, 1998; Piner 1998). VSOP observations will improve the measurements of component speeds in these sources. When combined with the geodetic data, they will provide us with images at four frequencies; allowing more accurate determination of the synchrotron spectra of the components and physical conditions in the jets. Any recently emerged components correlated with previous EGRET flares will be detected and position angles of newly emerged components will be accurately measured. Any moving components between the cores and the stationary components in 0202+149 and 1606+106 will be detected; this could help reveal the nature of stationary components in blazars.


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 AO2 proposals were submitted in May 1998, 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.
