6. A search for solar dark matter with the IceCube neutrino detector : Advances in data treatment and analysis technique
Sammanfattning : There is compelling observational evidence for the existence of dark matter in the Universe, including our own Galaxy, which could possibly consist of weakly interacting massive particles (WIMPs) not contained in the standard model (SM) of particle physics. WIMPs may get gravitationally trapped inside heavy celestial bodies of ordinary matter. LÄS MER
7. A Search for Solar Neutralino Dark Matter with the AMANDA-II Neutrino Telescope
Sammanfattning : 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
8. On the Search for High-Energy Neutrinos : Analysis of data from AMANDA-II
Sammanfattning : A search for a diffuse flux of cosmic neutrinos with energies in excess of 1014 eV was performed using two years of AMANDA-II data, collected in 2003 and 2004. A 20% evenly distributed sub-sample of experimental data was used to verify the detector description and the analysis cuts. LÄS MER
9. Preparations for the next solar WIMP Analysis with IceCube : Advances in simulation, filtering, event topology identification and analysis approach
Sammanfattning : In the year 2011 the construction of IceCube, a neutrino observatory buried in deep clear Antarctic ice, was completed. IceCube now consists of an array of 5160 digital light detection modules assembled on 86 strings, which encloses a instrumented volume of roughly 1~km$^3$ optimized for detection of neutrinos down to energies of 100~GeV.

10. Statistical Modelling and Inference for XENON1T
Sammanfattning : A great number of astrophysical observations suggests that of the matter in our universe, only a sixth is made up of known matter. The rest, named dark matter, has not been successfully identified. LÄS MER
