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

   Author : Pat Scott; Joakim Edsjö; Lars Bergström; Jan Conrad; Dan Hooper; Stockholms universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

4. 2. Supersymmetric Dark Matter : aspects of sfermion coannihilations

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

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE

6. 4. Dark matter electron interactions in detector materials

   Author : Einar Urdshals; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; effective theory; Dark matter; direct detection;

   Abstract : Dark Matter (DM) makes up 85% of the matter content of the universe, and its gravitational effects are seen on scales ranging from that of cosmology to that of galactic astrophysics. The nature of DM is, however, unknown. READ MORE

7. 5. Effects of Dark Matter in Astrophysical Systems

   Author : Stefan Clementz; Mattias Blennow; Tommy Ohlsson; Riccardo Catena; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark matter; Self-interactions; solar capture; helioseismology; inelastic dark matter; direct detection; indirect detection; Fysik; Physics;

   Abstract : When studying astrophysical structures with sizes ranging from dwarf galaxies to galaxy clusters, it becomes clear that there are vast amounts of unobservable gravitating mass. A compelling hypothesis is that this missing mass, which we call dark matter, consists of elementary particles that can be described in the same manner as those of the standard model of particle physics.
