1. Searches for Particle Dark Matter : Dark stars, dark galaxies, dark halos and global supersymmetric fits
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
2. Delving in the Dark : Searching for Signatures of Non-Standard Physics in Cosmological and Astrophysical Observables
Sammanfattning : 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. LÄS MER
Sammanfattning : Building design typically has a focus on energy use and economy. The indoor environment is often overlooked or simplified to such an extent that essential aspects are neglected. Additionally, introducing technologies for improving energy efficiency can also affect the indoor thermal climate and, in turn, the perceived indoor comfort. LÄS MER
4. Searches for Dark Matter with IceCube and DeepCore : New constraints on theories predicting dark matter particles
Sammanfattning : 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. LÄS MER
Sammanfattning : In the standard model of cosmology, the universe is currently dominated by dark energy in the form of the cosmological constant that drives the expansion to accelerate. While the cosmological constant hypothesis is consistent with all current data, models with dynamical behaviour of dark energy are still allowed by observations. LÄS MER
