Implications of High-Resolution Simulations on Indirect Dark Matter Searches
Lidia Pieri, Julien Lavalle, Gianfranco Bertone +1
We study the prospects for detecting the annihilation products of Dark Matter [DM] in the framework of the two highest-resolution numerical simulations currently available, i.e. {\…
Dark Matter Annihilation around Intermediate Mass Black Holes: an update
Gianfranco Bertone, Mattia Fornasa, Marco Taoso +1
The formation and evolution of Black Holes inevitably affects the distribution of dark and baryonic matter in the neighborhood of the Black Hole. These effects may be particularly…
Multi-messenger constraints on the annihilating dark matter interpretation of the positron excess
Miguel Pato, Lidia Pieri, Gianfranco Bertone
The rise in the energy spectrum of the positron ratio, observed by the PAMELA satellite above 10 GeV, and other cosmic ray measurements, have been interpreted as a possible signatu…
CMB constraints on Dark Matter models with large annihilation cross-section
S. Galli, F. Iocco, G. Bertone +1
The injection of secondary particles produced by Dark Matter (DM) annihilation around redshift 1000 would inevitably affect the process of recombination, leaving an imprint on Cosm…
The WIMP Forest: Indirect Detection of a Chiral Square
Gianfranco Bertone, C. B. Jackson, Gabe Shaughnessy +2
The spectrum of photons arising from WIMP annihilation carries a detailed imprint of the structure of the dark sector. In particular, loop-level annihilations into a photon and ano…
Anisotropy probe of galactic and extra-galactic Dark Matter annihilations
Mattia Fornasa, Lidia Pieri, Gianfranco Bertone +1
We study the flux and the angular power spectrum of gamma-rays produced by Dark Matter (DM) annihilations in the Milky Way (MW) and in extra-galactic halos. The annihilation signal…
