Francis Halzen of the University of Wisconsin will speak on “IceCube and the Discovery of High-Energy Extraterrestrial Neutrinos” at a physics colloquium on Wednesday, Feb. 26 at 4 p.m. in 124 Hasbrouck Laboratory.
The IceCube project transformed one cubic kilometer of natural Antarctic ice into a neutrino detector. The instrument detects 100,000 neutrinos per year in the GeV to PeV energy range. Among those, researchers have recently isolated a flux of extraterrestrial neutrinos. Halzen will discuss the instrument, the analysis of the data and the significance of the discovery of cosmic neutrinos.
