What We Can Do With 500,000 Type Ia Supernovae

While Type Ia Supernovae (SNIa) are one of the most mature cosmological probes, the next era promises to be extremely exciting in the number of different ways SNIa are used to measure various cosmological parameters. In this talk I will go over recent cosmological results from Pan-STARRS and The Dark Energy Survey.  I will then discuss upcoming experiments in the 2020s that will yield orders of magnitudes more SNIa, and the new understandings and capabilities to constrain systematic uncertainties at a level to match these statistics. I’ll discuss five different cosmological probes with SNIa: the conventional Hubble diagram for measuring dark energy, the distance ladder for measuring the Hubble constant, peculiar velocities and weak lensing for measuring sigma8, and strong lens measurements of H0 and other cosmological parameters. I’ll discuss the promise and challenges of these different approaches, and how quickly we will be able to leverage these results.
