Extending Fermi-LAT and H.E.S.S. Limits on Gamma-ray Lines from Dark Matter Annihilation
Stefano Profumo, Farinaldo S. Queiroz, Carlos E. Yaguna
Gamma-ray lines from dark matter annihilation (, where ) are always accompanied, at lower energies, by a continuum gamma-ray spectrum stemming both from radiativ…
Effect of Black Holes in Local Dwarf Spheroidal Galaxies on Gamma-Ray Constraints on Dark Matter Annihilation
Alma X. Gonzalez-Morales, Stefano Profumo, Farinaldo S. Queiroz
Recent discoveries of optical signatures of black holes in dwarf galaxies indicates that low-mass galaxies can indeed host intermediate massive black holes. This motivates the asse…
Stringent and Robust Constraints on the Dark Matter Annihilation Cross Section From the Region of the Galactic Center
Dan Hooper, Chris Kelso, Farinaldo S. Queiroz
For any realistic halo profile, the Galactic Center is predicted to be the brightest source of gamma-rays from dark matter annihilations. Due in large part to uncertainties associa…
