First Cosmology Results Using Type Ia Supernova from the Dark Energy Survey

Today, now 20 years after the discovery of the acceleration of the universe, the Dark Energy Survey (DES) Supernova Program has discovered thousands of Type Ia Supernovae (SNe Ia) useful for cosmological measurements.  In this talk I will present the first analysis of a small subset of 207 spectroscopically confirmed SNe Ia discovered during the first 3 years of the DES Supernova Program. I will show why this state of the art dataset provides constraints competitive to measurements using aggregate samples of >1000 SNe Ia, and I will forecast the full 5 year DES photometrically classified sample.
