Cosmology with Photometric Supernovae

Future wide-field, deep supernova surveys will discover thousands to tens of thousands of supernova each year, making spectroscopic follow-up observations of all SN candidates a challenging task with existing resources. Studies of supernova properties and cosmology will, therefore, necessitate a photometric determination of the supernova type, cosmological redshift, and the luminosity distance from light curve data alone.  I will discuss the feasibility of measuring cosmological parameters with photometric supernovae using data from current large surveys as well as detailed simulations from DES and LSST.
