Physics and Astronomy Colloquium

IceCube and the birth of high-energy neutrino astrophysics

Presented by Ignacio Taboada, Georgia Institute of Technology

IceCube is a TeV-PeV neutrino observatory operating at the Geographic South Pole. IceCube has discovered an all-sky, all-flavor, extragalactic neutrino flux. The origin of the sources responsible for these sources has remained a mistery. However, IceCube has identified two Active Galaxies as candidate sources: the blazar TXS 0506+06 and the Seyfert II NGC 1068. These two sources have significant differences in their observed electromagnetic and neutrino properties.

In this colloquium, I will describe the operation of IceCube as a neutrino telescope. I'll describe the properties of the all-sky, extragalacic flux. I'll review the observations of NGC 1068 and TXS 0506+056. I'll finish with my opinion of the future of this field.
