Indirect dark matter searches as a probe of degenerate particle spectra
Masaki Asano, Torsten Bringmann, Christoph Weniger
We consider the possibility that the cosmological dark matter consists of particles very close in mass to new colored particles below the TeV scale. While such a scenario is inhere…
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…
Galaxy Clusters and Gamma-Ray Lines: Probing Gravitino Dark Matter with the Fermi LAT
Xiaoyuan Huang, Gilles Vertongen, Christoph Weniger
If dark matter particles are not perfectly stable, their decay products might be seen in the cosmic-ray fluxes. A natural candidate for decaying dark matter is the gravitino in R-p…
Probing Dark Matter Decay and Annihilation with Fermi LAT Observations of Nearby Galaxy Clusters
Xiaoyuan Huang, Gilles Vertongen, Christoph Weniger
Galaxy clusters are promising targets for indirect dark matter searches. Gamma-ray signatures from the decay or annihilation of dark matter particles inside these clusters could be…
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…
Hunting Dark Matter Gamma-Ray Lines with the Fermi LAT
Gilles Vertongen, Christoph Weniger
Monochromatic photons could be produced in the annihilation or decay of dark matter particles. At high energies, the search for such line features in the cosmic gamma-ray spectrum…
