  1. 1. The Extremes of Neutrino Astronomy From Fermi Bubbles with IceCube to Ice Studies with ARIANNA

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Elisabeth Unger; Allan Hallgren; Olga Botner; Antonio Capone; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; astroparticle physics; neutrino telescopes; IceCube; Fermi bubbles; ARIANNA; horizontal propagation; surface wave propagation; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics; High Energy Physics; Högenergifysik;

    Sammanfattning : The Fermi bubbles are extended regions of hard gamma-ray emission which were discovered with Fermi-LAT data to exist above and below the Galactic Center. In order to explain the origin of the gamma-rays, different theories are proposed. LÄS MER

  2. 2. Exploring the Universe Using Neutrinos A Search for Point Sources in the Southern Hemisphere Using the IceCube Neutrino Observatory

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Rickard Ström; Uppsala universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; astroparticle physics; neutrino sources; neutrino telescopes; IceCube; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : Neutrinos are the ideal cosmic messengers, and can be used to explore the most powerful accelerators in the Universe, in particular the mechanisms for producing and accelerating cosmic rays to incredible energies. By studying clustering of neutrino candidate events in the IceCube detector we can discover sites of hadronic acceleration. LÄS MER

  3. 3. Neutrino emission from high-energy component gamma-ray bursts

    Detta är en avhandling från Uppsala : Department of Physics and Astronomy, Uppsala University

    Författare :Martino Olivo; Uppsala universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neutrino; GRB; IceCube; NATURAL SCIENCES Physics Astronomy and astrophysics Astroparticle physics; NATURVETENSKAP Fysik Astronomi och astrofysik Astropartikelfysik;

    Sammanfattning : Gamma-ray bursts (GRBs) are brief and sudden explosions radiating most of their energy in the soft γ-ray band ( 100 keV). In the context of multimessenger astroparticle physics recent observations of GRBs provide an excellent benchmark for testing theoretical models of high energy emission mechanisms. LÄS MER

  4. 4. A search for solar dark matter with the IceCube neutrino telescope

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Gustav Wikström; Stockholms universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark matter; neutrinos; neutrino telescopes; IceCube; NATURAL SCIENCES Physics Astronomy and astrophysics Astroparticle physics; NATURVETENSKAP Fysik Astronomi och astrofysik Astropartikelfysik; fysik; Physics;

    Sammanfattning : Dark matter particles in the form of supersymmetric Weakly Interacting Massive Particles (WIMPs) could accumulate in the centre of the Sun because of gravitational trapping. Pair-wise annihilations of WIMPs could create standard model particles out of which neutrinos could reach the Earth. LÄS MER

  5. 5. Searches for Dark Matter with IceCube and DeepCore New constraints on theories predicting dark matter particles

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Matthias Danninger; Stockholms universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark matter; neutrinos; neutrino telescopes; IceCube; DeepCore; dark matter experiments; Physics; fysik;

    Sammanfattning : The cubic-kilometer sized IceCube neutrino observatory, constructed in the glacial ice at the South Pole, searches indirectly for dark matter via neutrinos from dark matter self-annihilations. It has a high discovery potential through striking signatures. LÄS MER
