Dark Matter Identification using Gamma Rays from Dwarf Galaxies
Bibhushan Shakya, Maxim Perelstein
If the positron fraction and combined electron-positron flux excesses recently observed by PAMELA, Fermi and HESS have a dark matter origin, final state radiation (FSR) photons fro…
Antiprotons from Dark Matter: Effects of a Position-Dependent Diffusion Coefficient
Maxim Perelstein, Bibhushan Shakya
Energetic antiprotons in cosmic rays can serve as an important indirect signature of dark matter. Conventionally, the antiproton flux from dark matter decays or annihilations is ca…
Dark Matter Identification with Gamma Rays from Dwarf Galaxies
Maxim Perelstein, Bibhushan Shakya
If the positron fraction and combined electron-positron flux excesses recently observed by PAMELA, FERMI and HESS are due to dark matter annihilation into lepton-rich final states,…
Comment on Calculation of Positron Flux from Galactic Dark Matter
Maxim Perelstein, Bibhushan Shakya
Energetic positrons produced in annihilation or decay of dark matter particles in the Milky Way can serve as an important indirect signature of dark matter. Computing the positron…
