IceCube and the birth of high-energy neutrino astrophysics

The IceCube Neutrino Observatory instruments a cubic kilometer of Antarctic ice to explore the Universe through >TeV (10¹² eV) neutrinos. Completed in 2011, IceCube continuously monitors the entire sky (4π sr) with over 99% uptime. In this presentation, I will highlight IceCube’s major scientific achievements: the discovery of an all-sky flux of extragalactic neutrinos, the detection of neutrinos from the Milky Way, and evidence for astrophysical point sources, including the Seyfert 2 galaxy NGC 1068 and the blazar TXS 0506+056. I will also discuss ongoing work by the Georgia Tech group to extend astrophysical neutrino observations down to energies as low as 10 GeV (10¹⁰ eV) and conclude with a forward-looking perspective on this new field over the next decade.
