The experiment discovered a flux of neutrinos reaching us fr om the cosmos\, with energies more than a million times those of neutrinos produced at accelerator laboratories. These cosmic neutrinos are astronom ical messengers coming from some of the most violent processes in the univ erse and from the biggest explosions since the Big Bang. We will discuss t he IceCube telescope and highlight the recent discoveries that some high-e nergy neutrinos—and cosmic rays—originate from sources powered by rotating supermassive black holes.\n\nAbout Dr. Francis Halzen: \n\nFrancis Halzen is a Vilas and Gregory Breit Distinguished Professor of Physics at the Un iversity of Wisconsin–Madison. Born in Belgium\, Halzen received his Maste r’s and PhD degrees from the KUL Leuven\, Belgium\, and has been on the ph ysics faculty at UW–Madison since 1972\; in 2021\, Halzen was named a Vila s Research Professor\, one of the university’s most prestigious honors. He has been a fellow of the American Physical Society since 1994\, and is th e recipient of numerous awards\, including the 2014 Smithsonian American I ngenuity Award\, the 2015 Balzan Prize\, a 2018 Bruno Pontecorvo Prize\, t he 2019 IUPAP Yodh Prize\, the 2021 Bruno Rossi Prize of the American Astr onomical Society\, the 2021 Homi Bhabha Award\, and honorary doctorates at several universities.\n\nHalzen is the Principal Investigator of IceCube\ , a cubic-kilometer neutrino telescope buried in the Antarctic ice at the South Pole. IceCube’s first observations of high-energy cosmic neutrinos g arnered the 2013 Physics World Breakthrough of the Year Award. In Septembe r 2017\, IceCube detected a high-energy neutrino from the direction of a b lazar called TXS 0506+056. This was the first-ever evidence of a source of high-energy cosmic rays\, whose origins have been notoriously difficult t o pinpoint since they were discovered over one hundred years ago.\nA skill ed science communicator\, Halzen travels widely\, giving about 20 or more invited talks per year at conferences\, workshops\, and colloquia. He also gives regular public talks to local and national groups and interviews fo r television and radio. Halzen is the co-author of Quarks and Leptons\, a classic textbook on modern particle physics that continues to be used exte nsively throughout college campuses today. He has a large number of public ations to his credit and has written or edited several other books. His es say “Antarctic Dreams\,” about the early days of AMANDA\, IceCube’s precur sor\, was featured in The Best American Science Writing 2000.\n\nThe event will also be streaming live on YouTube\, but please note that questions a sked over the NSN-members-only Zoom Q&A will be prioritized.
