SUMMARY:Speaker: Maria Vincenzi (Duke University) - Title: Cosmological results from the Dark Energy Survey Supernova program
DESCRIPTION:Research Progress Meeting \nDate: May 9\, 2024 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Maria Vincenzi (Duke University) \nTitle:Cosmological results from the Dark Energy Survey Supernova program \nAbstract: 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. \nLooking 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. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239
