Description
The IceCube Neutrino Observatory is a cubic-kilometer neutrino detector built into the deep glacial ice at the geographic South Pole. Using an array of optical sensors, IceCube detects the Cherenkov light emitted by secondary charged particles produced by neutrino interactions. Following the initial discovery of a diffuse astrophysical neutrino flux a decade ago, recent searches have also identified the blazar TXS 0506+056 and the Seyfert galaxy NGC 1068 as candidate extragalactic neutrino sources. Furthermore, IceCube has recently found evidence for a neutrino flux from our own Galactic plane. We present an overview of IceCube's observations of galactic and extragalactic neutrinos and what these observations may tell us about their sources.
