  1. 31. 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

  3. 32. Reflective Equilibrium : An Essay in Moral Epistemology

    Författare :Folke Tersman; Lars Bergström; Wlodek Rabinowicz; Department of Philosophy Faculty of Humanities Stockholm University; []
    Nyckelord :HUMANIORA; HUMANITIES; coherence; Donald Davidson; epistemic justification; isolation argument; moral epistemology; moral knowledge; John Rawls; reflective equilibrium;

    Sammanfattning : In recent literature conceming the possibility of moral knowledge, it has been popular to apply coherentist accounts of epistemic justification to moral beliefs. This strategy is commonly associated with the notion of "reflective equilibrium" since the introductionof this term by John Rawls. LÄS MER

  4. 33. Weigh them all! : Cosmological searches for the neutrino mass scale and mass ordering

    Författare :Sunny Vagnozzi; Katherine Freese; Lars Bergström; Alessandra Silvestri; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neutrinos; neutrino mass; neutrino mass ordering; cosmology; cosmic microwave background; large-scale structure; galaxy surveys; dark energy; cosmic inflation; data analysis; teoretisk fysik; Theoretical Physics;

    Sammanfattning : The elusive neutrinos are among the most intriguing constituents of the particle zoo. The observation of neutrino flavour oscillations, indicating that neutrinos are massive, provides the only direct evidence for physics beyond the Standard Model. LÄS MER

  5. 34. Observations of nearby Galaxy Clusters with the Fermi Large Area Telescope : Towards the first Gamma Rays from Clusters

    Författare :Stephan Zimmer; Jan Conrad; Lars Bergström; Torsten Enßlin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Galaxy Clusters; Fermi-LAT; γ rays; Dark Matter; Cosmic Rays; fysik; Physics;

    Sammanfattning : Galaxy clusters are the most massive bound systems known in the Universe and are believed to have formed through large scale structure formation. They host relativistic cosmic-ray (CR) populations and are gravitationally bound by large amounts of Dark Matter (DM), both providing conditions in which high-energy gamma rays may be produced either via CR interactions with the intracluster medium or through the annihilation or decay of DM particles.

  7. 35. Three Realities : Women in different phases of drug abuse - a social psychological investigation

    Författare :Marie Bergström; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; gender; Applied and experimental psychology; social psychology; personality; drug addiction; Tillämpad och experimentell psykologi; women; DMTm;

    Sammanfattning : The purpose of this study was to systematically examine the social, cultural and psychological situation of a group of women with drug addiction, and to gain an understanding of it. Different theoretical perspectives were utilized in efforts to understand and explain why some young women start using drugs. LÄS MER
