Session 83 - Gravitational Lensing.
Display session, Friday, January 09
Measurement of time delays in gravitational lens systems combined with an independent measure of the lens strength and a model of the lensing potential provide a method for determining the angular diameter distance to the lens. Measurements in many lensing systems will allow the extraction of cosmological parameters from the resulting angular diameter distance-redshift relation. We report on the results of a 45 epoch time delay observation of the gravitational lens CLASS 1600+434 performed using the VLA at 8 GHz over the period 10 Oct 1996 -- 23 May 1997.
