Constraints on the dark matter annihilation scenario of Fermi 130 GeV gamma-ray line emission by continuous gamma-rays, Milky Way halo, galaxy clusters and dwarf galaxies observations
It was recently reported that there may exist monochromatic γ-ray emission at ∼ 130 GeV from the Galactic center in the Fermi Large Area Telescope data, which might be related with dark matter (DM) annihilation. In this work we carry out a comprehensive check of consistency of the results with …
