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. | |||

Understanding the formation and evolution of the Kepler Planets
The observed exoplanet population unveiled by Kepler is billions of years old, distinctly separated in time from the planet formation process that only lasted ~10-100 Myr. I will argue that atmospheric escape has been one of the key evolutionary drivers shaping the exoplanet population we observed today. By understanding how these planet evolve in time, I will show we can place some intriguing constraints on how they formed.

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.
