Astrophysics with neutrinos and other cosmic messengers
Speaker: Justin Vandenbroucke (University of Wisconsin)
Abstract: The IceCube Neutrino Observatory at the South Pole features a billion tons of ice as the detector material. A few years ago, IceCube discovered a flux of TeV-PeV neutrinos from the cosmos. By combining this new astrophysical messenger with others including gravitational waves and gamma rays, we can identify and determine the physics powering some of the most extreme objects in the universe, including nature’s own particle accelerators. This multi-messenger approach has provided evidence for the first identified source of the astrophysical neutrinos (powered by a black hole at the center of a distant galaxy), but there must be at least one hundred additional sources that are not yet identified. The origins of the astrophysical neutrinos therefore remain an outstanding mystery. I will present our ongoing studies of astrophysical neutrinos in a multi-messenger context and conclude with prospects for the future with IceCube-Gen2.
