Probing galaxy density profiles with future supernova surveys

In this paper we discuss the possibility of measuring the Hubble parameter and the slope of galaxy density profiles using future supernova data. With future supernova surveys such as the Supernova/Acceleration Probe (SNAP), large numbers of core-collapse supernovae will be discovered, a small fraction of which will be multiply imaged. Measurements of the image separation, flux ratio, time delay, and properties of the lens galaxy for these systems will provide tight constraints on the slope of galactic halos as well as providing complementary and independent information to other cosmological tests with respect to the Hubble parameter.
