Title: Optical Monitoring of Gravitationally Lensed Quasars

Abstract: We propose to continue our monitoring program of 16 gravitationally lensed quasars using the WIYN 3.5m telescope. The time-delay variability in gravitational lenses can be used to \it simultaneously study the Hubble constant, the average stellar mass, the structure and composition of galaxy halos, and the size and structure of quasar accretion disks. Recently developed analysis methods permit us to quantitatively analyze the light curves including both intrinsic and microlensing variability, and allow us to estimate the above quantities and their uncertainties. What we lack is data.
