1. Cosmological Dark Matter and the Isotropic Gamma-Ray Background Measurements and Upper Limits
Detta är en avhandling från Stockholm : Department of Physics, Stockholm UniversitySammanfattning : 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
2. Gamma-Ray Emission from Galaxy Clusters DARK MATTER AND COSMIC-RAYS
Detta är en avhandling från Stockholm : Department of Physics, Stockholm UniversitySammanfattning : The quest for the first detection of a galaxy cluster in the high energy gamma-ray regime is ongoing, and even though clusters are observed in several other wave-bands, there is still no firm detection in gamma-rays.To complement the observational efforts we estimate the gamma-ray contributions from both annihilating dark matter and cosmic-ray (CR) proton as well as CR electron induced emission.

3. Light from Dark Matter Hidden Dimensions, Supersymmetry, and Inert Higgs
Detta är en avhandling från Stockholm : FysikumSammanfattning : Recent observational achievements within cosmology and astrophysics have lead to a concordance model in which the energy content in our Universe is dominated by presumably fundamentally new and exotic ingredients – dark energy and dark matter. To reveal the nature of these ingredients is one of the greatest challenges in physics. LÄS MER
4. A Search for Solar Neutralino Dark Matter with the AMANDA-II Neutrino Telescope
Detta är en avhandling från Stockholm : FysikumSammanfattning : A relic density of Weakly Interacting Massive Particles (WIMPs) remaining from the Big Bang constitutes a promising solution to the Dark Matter problem. It is possible for such WIMPs to be trapped by and accumulate in gravitational potentials of massive dense objects such as the Sun. LÄS MER
5. Investigating the Dark Universe through Gravitational Lensing
Detta är en avhandling från Stockholm : Department of Astronomy, Stockholm UniversitySammanfattning : A variety of precision observations suggest that the present universe is dominated by some unknown components, the so-called dark matter and dark energy. The distribution and properties of these components are the focus of modern cosmology and we are only beginning to understand them. LÄS MER
