GBT14B-123

RadioAstron-GBT Space VLBI survey of AGN at the highest angular resolutions

Abstract

We request 180 hours of GBT time in the Semester 2014B and 2015A to continue a non-imaging Space VLBI survey of the bright AGN jet cores with RadioAstron at L/C/K bands. Early outcome of the survey demonstrates promising results and a high detection rate at long Space VLBI baselines.
The main goal of this project is to study physics of AGN cores and properties of ISM by observing AGNs up to the longest RadioAstron baseline projections of 30 Earth diameters and measuring the core's geometry and brightness temperature while taking the influence of the inter-stellar medium into full consideration.
