Sammanfattning : The detection of dark matter is a primary issue in today's astrophysics. Although the lightest supersymmetric particle, generally assumed to be a neutralino, is an excellent dark matter candidate, it is not easy to prove that such particles are the main component of galactic halos.

Sammanfattning : When studying astrophysical structures with sizes ranging from dwarf galaxies to galaxy clusters, it becomes clear that there are vast amounts of unobservable gravitating mass. A compelling hypothesis is that this missing mass, which we call dark matter, consists of elementary particles that can be described in the same manner as those of the standard model of particle physics.

Sammanfattning : With the ever increasing use of computers for critical systems, computer security, the protection of data and computer systems from intentional, malicious intervention, is attracting much attention. Among the methods for defence, intrusion detection, i.e. LÄS MER
Sammanfattning : While the dark matter has so far only revealed itself through the gravitational inﬂuence it exerts on its surroundings, there are good reasons to believe it is made up by WIMPs – a hypothetical class of heavy elementary particles not encompassed by the Standard Model of particle physics. The Inert Doublet Model constitutes a simple extension of the Standard Model Higgs sector. LÄS MER
Sammanfattning : In this PhD thesis we investigate various aspects of particle dark matter. The proper identification of dark matter developed during the second half of the twentieth century to become one of the biggest endeavours in modern physics and astronomy. LÄS MER
