Description

IceCube is a neutrino telescope built into the ice at the south pole. The detector is sensitive to "tracks" as produced by charged current interactions from muon neutrinos and "cascades" produced by other flavors and the neutral current. Due to recent machine-learning-based advances in reconstruction, the precision of the pointing and background rejection have improved significantly, and IceCube has been able to detect neutrino emission from the Galactic Plane. Since this detection, it has become possible to probe the flavor content of this excess which expands upon IceCube’s previous diffuse astrophysical flavor measurements. This talk discusses using IceCube to probe the flavor content of the Galactic Plane.
