1. A search for solar dark matter with the IceCube neutrino telescope
Abstract : Dark matter particles in the form of supersymmetric Weakly Interacting Massive Particles (WIMPs) could accumulate in the centre of the Sun because of gravitational trapping. Pair-wise annihilations of WIMPs could create standard model particles out of which neutrinos could reach the Earth. READ MORE

2. Examination of Dissociative Recombination Processes of Importance for Astrochemically Evolving Interstellar Clouds
Abstract : Each single moment a myriad of processes is taking place throughout the universe. A great deal of them has been found to be dissociative recombination (DR) reactions. In this thesis the major work described are related to experimental determination of reaction rates and how the reaction products splits up into their final fragments. READ MORE

3. 1D to 3D Magnetism in Quantum Materials: A study by Muons, Neutrons & X-rays
Abstract : A collection of works stretching from low- to three-dimensional magnetism are presented, studied mostly through muon spin rotation, relaxation and resonance (µ +SR). The theoretical background of this technique is outlined in Chapter 2, which introduces the subject from the muon particle as an astro[1]nomical particle to how they are produced here on Earth.

4. Observations of distant supernovae and cosmological implications
Abstract : Type Ia supernovae can be used as distance indicators for probing the expansion history of the Universe. The method has proved to be an efficient tool in cosmology and played a decisive role in the discovery of a yet unknown energy form, dark energy, that drives the accelerated expansion of the Universe.
