Cosmology and the Dark Matter Frontier
L. Bergstrom
A brief overview is given about some issues in current astroparticle physics, focusing on the dark matter (DM) problem, where the connection to LHC physics is particularly strong.…
New limits on dark matter annihilation from AMS cosmic ray positron data
Lars Bergstrom, Torsten Bringmann, Ilias Cholis +2
The AMS experiment onboard the International Space Station has recently provided cosmic ray electron and positron data with unprecedented precision in the range from 0.5 to 350 GeV…
Investigating Gamma-Ray Lines from Dark Matter with Future Observatories
Lars Bergström, Gianfranco Bertone, Jan Conrad +2
We study the prospects for studying line features in gamma-ray spectra with upcoming gamma-ray experiments, such as HESS-II, the Cherenkov Telescope Array (CTA), and the GAMMA-400…
Les Houches 2011: Physics at TeV Colliders New Physics Working Group Report
G. Brooijmans, B. Gripaios, F. Moortgat +141
We present the activities of the "New Physics" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 30 May-17 June, 2011). Our report includes new agreem…
Prospects of detecting gamma-ray emission from galaxy clusters: cosmic rays and dark matter annihilations
Anders Pinzke, Christoph Pfrommer, Lars Bergstrom
We study the possibility for detecting gamma-ray emission from galaxy clusters. We consider 1) leptophilic models of dark matter (DM) annihilation that include a Sommerfeld enhance…
Gamma-rays from dark matter annihilations strongly constrain the substructure in halos
Anders Pinzke, Christoph Pfrommer, Lars Bergstrom
Recently, it has been shown that electrons and positrons from dark matter (DM) annihilations provide an excellent fit to the Fermi, PAMELA, and HESS data. Using this DM model, whic…
