Lowering IceCube's energy threshold for point source searches in the southern sky

Abstract:

Observation of a point source of astrophysical neutrinos would be a“smoking gun”signature of a cosmic-ray accelerator. While IceCube has recently discovered a diffuseflux of astrophysical neutrinos, no localized point source has been observed. Previous IceCube searches for point sources in the southern sky were restricted by either an energy threshold above a few hundred TeV or poor neutrino angular resolution. Here we present a search for southern sky point sources with greatly improved sens...
