Session 47 - Microlensing.
Display session, Tuesday, January 16
North Banquet Hall, Convention Center
The gravitational lens MG0414+053 is a well established lens candidate for which much observational and lens modelling work has been done. Detection of a time delay in this system would allow for more tightly constrained models of the lensing potential and a measurement of the angular diameter distance to the lens. Such measurements can be used to probe the angular diameter distance--redshift relation on large scales thereby revealing information about cosmological parameters (Ømega_0, \Lambda, and H_0). We report on the results of an 82 epoch time delay observation of the gravitational lens MG0414+053 at 8 GHz that was carried out at the VLA during the period 9 Mar 1994--1 Jan 1995.
