Gamma-ray and Radio Constraints of High Positron Rate Dark Matter Models Annihilating into New Light Particles
Lars Bergstrom, Gianfranco Bertone, Torsten Bringmann +2
The possibility of explaining the positron and electron excess recently found by the PAMELA and ATIC collaborations in terms of dark matter (DM) annihilation has attracted consider…
Impacts of WIMP dark matter upon stellar evolution: main-sequence stars
Pat Scott, Malcolm Fairbairn, Joakim Edsjö
The presence of large amounts of WIMP dark matter in stellar cores has been shown to have significant effects upon models of stellar evolution. We present a series of detailed grid…
New Positron Spectral Features from Supersymmetric Dark Matter - a Way to Explain the PAMELA Data?
Lars Bergstrom, Torsten Bringmann, Joakim Edsjo
The space-borne antimatter experiment PAMELA has recently reported a surprising rise in the positron to electron ratio at high energies. It has also recently been found that electr…
Pre-launch estimates for GLAST sensitivity to Dark Matter annihilation signals
E. A. Baltz, B. Berenji, G. Bertone +25
We investigate the sensitivity of the Gamma-ray Large Area Space Telescope (GLAST) to indirectly detect weakly interacting massive particles (WIMPs) through the -ray signal that…
Low mass stellar evolution with WIMP capture and annihilation
Pat Scott, Joakim Edsjö, Malcolm Fairbairn
Recent work has indicated that WIMP annihilation in stellar cores has the potential to contribute significantly to a star's total energy production. We report on progress in simula…
Significant Gamma Lines from Inert Higgs Dark Matter
Michael Gustafsson, Erik Lundstrom, Lars Bergstrom +1
One way to unambiguously confirm the existence of particle dark matter and determine its mass would be to detect its annihilation into monochromatic gamma-rays in upcoming telescop…
