Title:Cosmological results from the Dark Energy Survey Supernova program
Abstract: The Dark Energy Survey Supernova sample is the largest and deepest Type Ia Supernova (SN Ia) sample from a single telescope to date. It includes 1600 photometrically identified SNe Ia with high-quality multi-band light curves and spectroscopic redshifts. With a redshift range spanning between 0.1 to 1.2 and a well-defined selection function, this SN sample constitutes an ideal dataset for cosmology. In my talk, I will present the cosmological results from this unique sample and show that DES SNe, combined with publicly available low-z SN samples, provides excellent constraints on the Dark Energy equation of state from SN Ia.
Looking towards the future, I will discuss how future optical ground-based surveys like Rubin, and space-based near-infrared observatories like the Nancy Grace Roman Space Telescope, will revolutionise SN Ia cosmology and potentially answer some of the most pressing questions of modern cosmology.
