11. Observations of nearby Galaxy Clusters with the Fermi Large Area Telescope : Towards the first Gamma Rays from Clusters
Abstract : Galaxy clusters are the most massive bound systems known in the Universe and are believed to have formed through large scale structure formation. They host relativistic cosmic-ray (CR) populations and are gravitationally bound by large amounts of Dark Matter (DM), both providing conditions in which high-energy gamma rays may be produced either via CR interactions with the intracluster medium or through the annihilation or decay of DM particles.

12. Searching for Gamma Rays from Galaxy Clusters with the Fermi Large Area Telescope : Cosmic Rays and Dark Matter
Abstract : In this licentiate thesis, I report a search for GeV γ rays towards the location of Galaxy clusters. I mainly discuss the results of a search for cosmic-ray (CR) induced γ-ray emission but also briefly elaborate on a related study, searching for Dark Matter (DM)-induced γ-ray emission from Galaxy clusters.

14. The Book of Hours of Johannete Ravenelle and the Parisian Book Illumination Around 1400
Abstract : Within the French book of hours C 517e in the manuscript collection of the University Library in Uppsala, the name of the owner, Johannete Ravenelle, appears in a prayer. Examination of the decoration, miniatures and texts demonstrates that ms C 517e is consistent with Parisian art and books of hours around 1400. READ MORE

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