IceCube is a very-high-energy neutrino telescope operating at the South Pole. IceCube monitors the full sky, all the time in search of neutrinos of astrophysical origin. IceCube has made several ground breaking observations.

In 2013, IceCube discovered an all-sky istropic flux of high-energy flux neutrinos. Most of these neutrinos are expected to be of extragalactic origin. Evidence for neutrino emission has been found for two active galaxies, the blazar TXS 0506+056 (2018) and NGC 1068 (2022). The origin of the all-sky extragalactic flux is not yet understood. In 2023, IceCube reported evidence of neutrino emission by our own galaxy, the Milky Way.

The Taboada group uses IceCube data to search for neutrino sources that can explain the origin of the astrophysical neutrino diffuse flux.
