    Abstract : 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. READ MORE

  4. 2. Search for Gamma-ray Lines from Dark Matter with the Fermi Large Area Telescope

    Author : Tomi Ylinen; Mark Pearce; Jan Conrad; Staffan Carius; James T. Linnemann; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fermi; Large Area Telescope; gamma-rays; dark matter; spectral lines; beam test; Physics; Fysik; Astroparticle physics; Astropartikelfysik;

    Abstract : Dark matter (DM) constitutes one of the most intriguing but so far unresolved issues in physics. In many extensions of the Standard Model of particle physics, the existence of a stable Weakly Interacting Massive Particle (WIMP) is predicted. The WIMP is an excellent DM particle candidate.

  5. 3. Statistical characteristics of two-dimensional and quasigeostrophic turbulence

    Author : Andreas Vallgren; Erik Lindborg; Johan Nilsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; two-dimensional turbulence; decaying turbulence; quasigeostrophic turbulence; direct numerical simulation DNS ; coherent vortices; energy cas- cade; enstrophy cascade; intermittency; massively parallel simulations; Non-linear dynamics; chaos; Icke-linjär dynamik; kaos;

    Abstract : Two codes have been developed and implemented for use on massively parallelsuper computers to simulate two-dimensional and quasigeostrophic turbulence.The codes have been found to scale well with increasing resolution and width ofthe simulations. READ MORE

  6. 4. Studies of Cellular Regulatory Mechanisms : from Genetic Switches to Cell Migration

    Author : Maria Werner; Erik Aurell; Ulrich Gerland; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasma physics; Plasmafysik;

    Abstract : Cellular behaviour depends ultimately on the transcription of genes. If we know how transcription is controlled we have a better chance of understanding cellular processes. This thesis presents six studies, all concerning cellular regulatory mechanisms. One study is purely experimental and five are computational studies. READ MORE
