Evidence for indirect detection of dark matter from galaxy clusters in Fermi $\gamma$-Ray data
We search for spectral features in Fermi-LAT gamma-rays coming from regions corresponding to eighteen brightest nearby galaxy clusters determined by the magnitude of their signal line-of-site integrals. We observe a double peak-like excess over the diffuse power-law background at photon energies 110...
