Mapping the Milky Way with Neutrinos

The IceCube Neutrino Observatory is a cubic-kilometer neutrino detector located at the geographic South Pole. It first identified neutrinos from outside our solar system in 2013, and in last decade two active galaxies have been identified as neutrinos source candidates. However, the majority of the astrophysical flux remains unexplained. Recently, a new sample of neutrinos has been used to make the first observation of the Galactic plane in high-energy neutrinos.  These neutrinos can be produced when cosmic rays interact at their acceleration sites and during propagation through the interstellar medium. This observation was enabled by machine-learning techniques that improved the selection efficiency and angular resolution of cascade-like neutrino events.
