Diffuse Gamma Ray Background from Annihilating Dark Matter in Density Spikes around Supermassive Black Holes
Alexander Belikov, Joseph Silk
Dark matter annihilation is proportional to the square of the density and is especially efficient in places of highest concentration of dark matter, such as dark matter spikes. The…
Neutron injection during primordial nucleosynthesis alleviates the primordial 7Li problem
Daniel Albornoz Vasquez, Alexander Belikov, Alain Coc +2
We present a parametrized study of the effects of free thermal neutron injection on primordial nucleosynthesis, where both the rate and the time scale of injection are varied. This…
The Isotropic Radio Background and Annihilating Dark Matter
Dan Hooper, Alexander V. Belikov, Tesla E. Jeltema +3
Observations by ARCADE-2 and other telescopes sensitive to low frequency radiation have revealed the presence of an isotropic radio background with a hard spectral index. The inten…
The Contribution Of Inverse Compton Scattering To The Diffuse Extragalactic Gamma-Ray Background From Annihilating Dark Matter
Alexander V. Belikov, Dan Hooper
In addition to gamma-rays, dark matter annihilation products can include energetic electrons which inverse Compton scatter with the cosmic microwave background to produce a diffuse…
Identifying Dark Matter Annihilation Products In The Diffuse Gamma Ray Background
Scott Dodelson, Alexander V. Belikov, Dan Hooper +1
Annihilation of cosmologically distributed dark matter is predicted to produce a potentially observable flux of high energy photons. Neglecting the contribution from local structur…
