  1. 6. Simulation of birefringence effects for high-energy neutrino detectors

    University essay from Uppsala universitet/Högenergifysik

    Author : Nils Heyer; [2021]
    Keywords : astroparticle physics; radio detection; high-energy neutrinos; birefringence;

    Abstract : The detection of high-energy neutrinos in the E > O(PeV) range requires newdetection techniques in order to cope with the decreasing flux. The radio detectionmethod uses Askaryan emission to detect these neutrinos. READ MORE

  3. 7. Measurement of the snow accumulation in Antarctica with a neutrino radio detector and extension to the measurement of the index-of-refraction profile

    University essay from Uppsala universitet/Högenergifysik

    Author : Jakob Beise; [2021]
    Keywords : Askaryan; UHE neutrinos; in-ice radio detection; in-situ detector calibration; deep learning; radio neutrino detector; ARIANNA;

    Abstract : High-energy neutrino physics offers a unique way to investigate the most violent phenomena in our universe. The detection of energies above E > 1017 eV is most efficient using the Askaryan effect, where a neutrino-induced particle shower produces coherent radio emission that is detectable with radio antennas.

  4. 8. In-situ calibration device of firn properties for Askaryan neutrino detectors

    University essay from Uppsala universitet/Högenergifysik

    Author : Jakob Beise; [2021]
    Keywords : Askaryan; UHE neutrinos; in-ice radio detection; in-situ detector calibration; deep learning; radio neutrino detector; ARIANNA;

    Abstract : Simulations have demonstrated that high-energy neutrinos (E > 1017 eV) are detected cost-efficiently via the Askaryan effect in ice, where a particle cascade induced by the neutrino interaction produces coherent radio emission that can be picked up by antennas installed below the surface. A good knowledge of the near surface ice (aka firn) properties is required to reconstruct the neutrino properties. READ MORE

  5. 9. Dark Matter – Direct Detection and Capture in the Sun

    University essay from KTH/Fysik

    Author : Erika Lind; [2020]
    Keywords : Dark matter; direct detection; indirect detection; solar capture; inelastic dark matter; Mörk materia; direkt detektion; indirekt detektion; solinfångning; inelastisk mörk materia;

    Abstract : Dark matter has been inferred from various observations such as in galaxy clusters, flat galactic rotation curves, gravitational lensing measurements and the cosmic microwave background. Despite overwhelming observational evidence and ongoing searches, a clear signal of dark matter has not yet been detected. READ MORE

  6. 10. Constraints on the Kaluza-Klein Photon as a Dark Matter Candidate from the IceCube Collaboration Results

    University essay from Uppsala universitet/Högenergifysik

    Author : Miquel Colom i Bernadich; [2019]
    Keywords : dark matter; WIMP; Kaluza-Klein; IceCube; neutrinos; muon neutrinos; muons;

    Abstract : New constraints on the scattering cross sections of the Kaluza Klein photon as a darkmatter candidate, its annihilation rate in the Sun and the resulting muon flux on Earth are derived.For this purpose, data collected in the IceCube Neutrino Observatory during 532 days of exposurein the austral winters between 2011 and 2014 have been analyzed with Poisson confidence intervals (J.
