Scientific paper

The observational properties of MG0414+0534 strongly suggest that it is a gravitationally lensed object: the four-component morphology, the radio/optical flux densities, the spectral indices of the four components, and the optical detection of the lensing galaxy. Detection of the three independent time delays in this system would allow for more tightly constrained models of the lensing potential and (ultimately) estimation of H0. In order to make this measurement, we are undertaking a series of approximately 60 VLA observations at 15 GHz extending over a total of eight months. We will present the resulting light-curves and discuss the measurement of the time delay from them.
