Proposal Abstract

We propose to observe a sample of 21 radio faint (0.02 <= S_{1.6 GHz} <= 0.05) quasars using a modified phase referencing technique. The sources are selected to be accessible to 18 cm space VLBI by the presence (within 1 degree) of a nearby strong reference (JVAS) source.

The main objectives of this work are:

-- To begin a study of the possible luminosity dependence and cosmological evolution of compact radio source properties with the highest angular resolution over a wide range in redshift

-- To demonstrate feasability of a new modification of phase-referencing VLBI which might considerably enhance the scientific outcome of VSOP and future Space VLBI missions

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.
