Astrophysical Neutrinos and How to Find Them - With Jenni Adams

Explore the fascinating world of astrophysical neutrinos and their detection in this comprehensive lecture by Jenni Adams. Delve into the IceCube collaboration, a massive telescope buried in Antarctica's crystal-clear ice, designed to detect these elusive particles. Learn how neutrinos act as cosmic messengers, traveling through the Universe while barely interacting with matter, and discover the precise instruments required for their detection. Understand the connection between neutrinos and high-energy cosmic sources, some a million times more energetic than our sun. Examine the fields of astroparticle physics and cosmology, exploring both theoretical and observational aspects. Gain insights into various topics, including ghost particles, neutrino types, large detectors, Cherenkov light, cosmic rays, and the challenges of distinguishing neutrino signals from background noise. This talk, recorded on January 27, 2022, offers a comprehensive overview of cutting-edge research in astrophysical neutrino detection and its implications for our understanding of the Universe.
