Conservative upper limits on WIMP annihilation cross section from Fermi-LAT -rays
F. Donato, F. Calore, V. De Romeri
The spectrum of an isotropic extragalactic -ray background (EGB) has been measured by the Fermi-LAT telescope at high latitudes. Two new models for the EGB are derived from the…
Spectral cutoffs in indirect dark matter searches
Christoph Weniger, Torsten Bringmann, Francesca Calore +1
Indirect searches for dark matter annihilation or decay products in the cosmic-ray spectrum are plagued by the question of how to disentangle a dark matter signal from the omnipres…
On the Relevance of Sharp Gamma-Ray Features for Indirect Dark Matter Searches
Torsten Bringmann, Francesca Calore, Gilles Vertongen +1
Gamma rays from the annihilation of dark matter particles in the Galactic halo provide a particularly promising means of indirectly detecting dark matter. Here, we demonstrate that…
