  1. 1. Searches for Particle Dark Matter : Dark stars, dark galaxies, dark halos and global supersymmetric fits

    Författare :Pat Scott; Joakim Edsjö; Lars Bergström; Jan Conrad; Dan Hooper; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dark matter; supersymmetry; gamma rays; dwarf galaxies; stellar evolution; cosmological perturbations; phase transitions; statistical techniques; Astroparticle physics; Astropartikelfysik; Astroparticle physics; Astropartikelfysik; Cosmology; Kosmologi; Elementary particle physics; Elementarpartikelfysik; Computational physics; Beräkningsfysik; Formation and development of stars; Stjärnors bildning och utveckling; High energy astrophysics; Högenergiastrofysik; teoretisk fysik; Theoretical Physics;

    Sammanfattning : The identity of dark matter is one of the key outstanding problems in both particle and astrophysics. In this thesis, I describe a number of complementary searches for particle dark matter. LÄS MER

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

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

    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

  3. 3. Supersymmetric Dark Matter : aspects of sfermion coannihilations

    Författare :Mia Schelke; Joakim Edsjö; Nicolao Fornengo; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supersymmetry; Dark Matter; Physics; Fysik;

    Sammanfattning : There is very strong evidence that ordinary matter in the Universe is outweighed by almost ten times as much so-called dark matter. Dark matter does neither emit nor absorb light and we do not know what it is. LÄS MER

  4. 4. Cosmological Dark Matter and the Isotropic Gamma-Ray Background : Measurements and Upper Limits

    Författare :Alexander Sellerholm; Jan Conrad; Karl Mannheim; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dark matter theory; dark matter simulations; dark matter experiments; isotropic gamma-ray background; Fermi gamma-ray space telescope; Astroparticle physics; Astropartikelfysik; teoretisk fysik; Theoretical Physics;

    Sammanfattning : This thesis addresses the isotropic diffuse gamma-ray background, as measured by the Fermi gamma ray space telescope, and its implications for indirect detection of dark matter. We describe the measurement of the isotropic background, including also an alternative analysis method besides the one published by the Fermi-LAT collaboration. LÄS MER

  5. 5. Unveiling the nature of dark matter with direct detection experiments

    Författare :Vanessa Zema; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NaI; phenomenology; annual-modulation; direct-detection; cryogenics; COSINUS; polarised-nuclei; CRESST; dark-matter; phonons;

    Sammanfattning : The desire of discovery is an anthropic need which characterises and connects the human being over the eras. In particular, observing the sky is an instinctive drive exerted by the curiosity of the mysteries which it retains. LÄS MER
