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

SUMMARY:Speaker: Deborah Harris (York/FNAL) - Title: Precision Neutrino Oscillation Measurements: Are we there yet?
DESCRIPTION:Research Progress Meeting \nDate: May 28\, 2024 \nTime: 4:00- 5:00 pm  \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Deborah Harris (York/FNAL) \nTitle: Precision Neutrino Oscillation Measurements: Are we there yet? \nAbstract: Neutrino Oscillations\, one of the precious few signatures of beyond the standard model physics\, offer an exciting opportunity to study the universe. Neutrino oscillation measurements can give us new insight into what generate particle masses and what might generate the abundance of matter over antineutrino that we currently enjoy. Making precision oscillation measurements is challenging though\, in part due to their miniscule probability to interact with matter. The Deep Underground Neutrino Experiment (DUNE)\, currently under construction\, aims to make precision measurements of neutrino oscillations across a broad range of neutrino energies\, with a goal of not only getting precise oscillation parameters in the new standard “3-neutrino-flavour paradigm” but also to test the framework itself. Making precision oscillation measurements also requires a thorough understanding of the way neutrinos interact in nuclei in order to measure the oscillation probability as a function of neutrino energy. This talk will review recent progress on DUNE as well as a few recent neutrino interaction measurements from MINERvA that are helping to lay the foundations of future oscillation measurements. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Emma Tolley (EPFL) - Title: Radio Cosmology: Imaging the Cosmic Dawn
DESCRIPTION:Research Progress Meeting \nDate: May 30\, 2024 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Emma Tolley (EPFL) \nTitle: Radio Cosmology: Imaging the Cosmic Dawn \nAbstract: Radio astronomers are engaged in ambitious new projects to detect faster\, fainter\, and more distant astrophysical phenomena. The flagship project is the Square Kilometer Array Observatory (SKAO). The SKAO will use thousands of individual radio receivers linked through interferometry to create the world’s largest radio telescope with unprecedented sensitivity\, field of view\, and survey speed\, allowing us to map the neutral hydrogen throughout our Universe from nearby galaxies to the Cosmic Dawn epoch when stars and galaxies first formed. However\, as a groundbreaking observational facility\, SKA introduces new astrophysical\, computational\, and data analysis challenges. I present an overview of computational challenges and solutions for the SKAO\, new techniques for image synthesis\, and applications of AI in 21cm cosmology experiments. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239
