1. 16. Dark Matter in the Solar System, Galaxy, and Beyond

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

   Sammanfattning : 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. LÄS MER

3. 17. Search for low mass WIMPs with the AMANDA neutrino telescope

   Författare :Anna Davour; Olga Botner; Carlos de los Heros; Mark Pearce; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; dark matter; WIMP; neutrino detection; AMANDA; supersymmetry; Fysik; Physics; Fysik; High Energy Physics; Högenergifysik;

   Sammanfattning : Recent measurements show that dark matter makes up at least one fifth of the total energy density of the Universe. The nature of the dark matter is one of the biggest mysteries in current particle physics and cosmology. LÄS MER

4. 18. Dark matter signal normalisation for dwarf spheroidal galaxies : A frequentist analysis of stellar kinematics for indirect Dark Matter searches

   Författare :Andrea Chiappo; Jan Conrad; Piero Ullio; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dark matter; dwarf galaxies; kinematics and dynamics of galaxies; fysik; Physics;

   Sammanfattning : Indirect detection strategies of Dark Matter (DM) entail searching for signals of DM annihilation or decay, typically in the form of excess positrons or high-energy photons above the astrophysical background, originating from (inferred) DM-rich environments. Due to their characteristics, dwarf spheroidal satellite galaxies (dSphs) of the Milky Way are considered very promising targets for indirect particle DM identification. LÄS MER

5. 19. Indirect Searches for Galactic Dark Matter with IceCube-DeepCore and PINGU

   Författare :Martin Wolf; Chad Finley; David Milstead; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark Matter; Galactic Center; IceCube; DeepCore; PINGU;

   Sammanfattning : The cubic-kilometer sized IceCube neutrino observatory is burieddeep in the glacial ice at the Earth’s South Pole. Its low-energyextension array DeepCore enables physicists to search indirectlyfor light Dark Matter (DM) particles with masses as low as tensof GeV/c2 situated within our home galaxy, the Milky Way.

7. 20. Rapid detection of drug resistance and genetic characterisation of Mycobacterium tuberculosis isolates in Honduras

   Författare :Senia Rosales; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: New challenges for tuberculosis (TB) control are emerging in the 21st century. The deadly combination TB/HIV as well as the development and spread of new forms of drug resistance are some examples. In this context, the timely detection of TB cases, especially of those with resistant TB is important. LÄS MER
