1. Observations of young core collapse supernova remnants
Sammanfattning : Studies of young remnants offer an opportunity to test theoretical models of stellar evolution, explosion models and nucleosynthesis, as well as our understanding of the compact objects in the centre of the exploded stars.The first part of the thesis involves observations of the Crab nebula.

2. Facets of Fun: On the Design of Computer Augmented Entertainment Artifacts
Sammanfattning : This thesis discusses the design of interactive entertaining artifacts such as computer games and computer augmented toys, games and objects. The aim has been to find and/or develop design tools i.e. LÄS MER
3. Molecules at stellar death: from the winds of massive evolved stars to supernova remnants
Sammanfattning : Massive stars play a key role in the chemical and dust budget of the galaxy, producing heavy elements, molecules, and dust. At the end of their lives they evolve through stages of significant mass-loss which affect the subsequent evolution of the star, including whether or not it will eventually explode as a supernova (SN). LÄS MER
4. Supernova remnants and their pulsar wind nebulae
Sammanfattning : Massive stars die in powerful stellar explosions, so-called supernovae. In most cases, a neutron star or a black hole is expected to form in the center. The ejected material in these explosions expands out into the surroundings for tens of thousands of years, forming a supernova remnant. If a rapidly rotating neutron star, i. LÄS MER
5. Phenomenological Studies on Supersymmetry and the Strong Force
Sammanfattning : In this thesis, we first consider the phenomenology of R-parity violating supersymmetric extensions of the Standard Model. Specifically, a large number of Lepton and Baryon Number violating decays of sparticles to particles are implemented in the Pythia event generator. LÄS MER
