New Results from the DES 5-year Photometric Supernova Sample
Abstract
We present analysis updates from the Dark Energy Survey - Supernova Program (DES-SN). Our cosmological analysis ('DES-SN5YR') uses a sample of approximately two thousand photometrically-typed (0.02 < z < 1.1) Type Ia supernovae (SNe Ia) from the full five years of DES-SN, combined with a low-redshift sample from multiple local surveys. We highlight key features of our cosmological analysis with a focus on systematics control.
