  2. 11. Dark Matter in the Solar System, Galaxy, and Beyond

    Author : Axel Widmark; Jens Jasche; Malcolm Fairbairn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dark matter: phenomenology; dark matter: indirect detection; dark matter: particle nature; Galactic dynamics; Galactic composition; Theoretical Physics; teoretisk fysik;

    Abstract : There is evidence that dark matter constitutes a majority of the Universe's matter content. Yet, we are ignorant about its nature. Understanding dark matter requires new physics, possibly in the form of a new species of fundamental particles. READ MORE

  4. 12. Dark matter in and around stars

    Author : Sofia Sivertsson; Tommy Ohlsson; Steen Hansen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark matter; early universe; Astroparticle physics; Astropartikelfysik;

    Abstract : There is by now compelling evidence that most of the matter in the universe is in the form of dark matter, a form of matter quite different from the matter we experience in every day life. The gravitational effects of this dark matter have been observed in many different ways but its true nature is still unknown. READ MORE

  5. 13. Delving in the Dark : Searching for Signatures of Non-Standard Physics in Cosmological and Astrophysical Observables

    Author : Janina J. Renk; Joakim Edsjö; Pat Scott; Felix Kahlhöfer; David F. Mota; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cosmology; gravitation; Galileon; dark energy; dark matter; cosmic superstrings; neutrino mass; parameter inference; teoretisk fysik; Theoretical Physics;

    Abstract : The dark sectors of our Universe, dark matter and dark energy, together constitute about 96 % of the total energy content of the Universe. To date, we only have observational evidence for their existence. READ MORE

  6. 14. Enhancing Direct Searches for Dark Matter : Spatial-Temporal Modeling and Explicit Likelihoods

    Author : Bart Eduard Jan Pelssers; Jan Conrad; Jochen Schieck; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark matter; direct detection; statistical analysis; fysik; Physics;

    Abstract : Astronomical and cosmological observations on different scales point to the existence of dark matter. In the current cosmological paradigm this dark matter accounts for about 26% of the energy-density of the universe, yet has not been directly observed. READ MORE

  7. 15. Dark Matter in the Galactic Halo : A Search Using Neutrino Induced Cascades in the DeepCore Extension of IceCube

    Author : Henric Taavola; Olga Botner; Allan Hallgren; Carlos Perez de los Heros; Jodi Cooley; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dark matter; WIMP; neutralino; MSSM; neutrino telescope; IceCube; DeepCore; Galactic halo; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : A search for Weakly Interacting Massive Particles (WIMPs) annihilating in the dark matter halo of the Milky Way was performed, using data from the IceCube Neutrino Observatory and its low-energy extension DeepCore. The data were collected during one year between 2011 to 2012 corresponding to 329.1 days of detector livetime. READ MORE
