Constraining the dark matter contribution of γ rays in clusters of galaxies using Fermi -LAT data

The authors analyze 12 years of Fermi-LAT data for 49 galaxy clusters to look for a \ensuremath{\gamma}-ray signal between 500 MeV and 1 TeV due to dark matter annihilation. Physically motivated dark mater density distribution templates and a thorough statistical approach lead to a low significance signal, unlikely to be due to dark matter processes.
