Search for contained neutrino events at energies greater than 1 TeV in 2 years of data

Introduction The IceCube Neutrino Observatory was designed primarily to search for high-energy (TeV–PeV) neutrinos produced in distant astrophysical objects. A search for >100 TeV neutrinos interacting inside the instrumented volume has recently provided evidence for an isotropic flux of such neutrinos. At lower energies, IceCube collects large numbers of neutrinos from the weak decays of […]

IceCube Oscillations: 3 years muon neutrino disappearance data

Introduction In the 1990s, Super-Kamiokande’s measurements of atmospheric neutrinos led to the acceptance of the mass-induced oscillation model. As of today, the three mixing angles, the solar mass splitting and the absolute value of the atmospheric mass splitting that control the oscillation phenomenon have been measured. The existence of CP-violation and the ordering of the […]

Search for contained neutrino events at energies above 30 TeV in 2 years of data

Introduction Neutrino observations are a unique probe of the universe’s highest energy phenomena: neutrinos are able to escape from dense environments that photons cannot and are unambiguous tracers of hadronic interaction processes, in particular the acceleration of cosmic rays. As cosmic ray protons and nuclei are accelerated, they interact with gas and background light to […]

IceCube-40 String Data

Searching for a Diffuse Flux of Astrophysical Muon Neutrinos One of the main strategies used to look for astrophysical neutrinos with IceCube is the search for a diffuse flux of high-energy neutrinos from unresolved sources. A hypothetical diffuse astrophysical muon neutrino flux would have a harder energy spectrum than atmospheric muon neutrino backgrounds. Therefore, evidence […]

IceCube-22 Solar WIMP Data

Searching for Muon Neutrinos from Dark Matter Annihilations in the Sun Relic dark matter in the galactic halo may become gravitationally trapped in the Sun and accumulate in its center, where it can annihilate each other, producing standard model particles, which may decay creating neutrinos. Neutrinos can escape the Sun and reach Earth. Icecube indirectly […]

AMANDA 7 Year Data

Introduction The Antarctic Muon And Neutrino Detector Array (AMANDA) is an optical Cherenkov detector consisting of 677 optical modules arranged in 19 strings frozen ~1.5 km — ~2 km deep in the ice sheet at the geographic South Pole. Each optical module contains a 20 cm photomultiplier tube surrounded by a glass pressure sphere housing. […]
