The gamma-ray and neutrino emissions from dark matter (DM) annihilation in galaxy clusters are studied. After about one year of operation of Fermi-LAT, several nearby clusters are reported with stringent upper limits of GeV gamma-ray emission. We use the Fermi-LAT upper limits of these clusters to constrain the DM model parameters. We find that the DM model distributed with substructures predicted in cold DM scenario is strongly constrained by Fermi-LAT gamma-ray data. Especially for the…

Galaxy Clusters as Reservoirs of Heavy Dark Matter and High-Energy Cosmic Rays: Constraints from Neutrino Observations
Galaxy Clusters (GCs) are the largest reservoirs of both dark matter and cosmic rays (CRs). Dark matter self-annihilation can lead to a high luminosity in gamma rays and neutrinos, enhanced by a

Constraints on the dark matter annihilation from Fermi-LAT observation of M31
Gamma-ray is a good probe of dark matter (DM) particles in the Universe. We search for the DM annihilation signals in the direction of the Andromeda galaxy (M31) using 7.5 year Fermi-LAT pass 8 data.
Hunting dark matter gamma-ray lines with the Fermi LAT
Monochromatic photons could be produced in the annihilation or decay of dark matter particles. At high energies, the search for such line features in the cosmic gamma-ray spectrum is essentially
Future sensitivity of neutrino telescopes to dark matter annihilations from the cosmic diffuse neutrino signal
Cosmological observations and cold dark matter N-body simulations indicate that our Universe is populated by numerous halos, where dark matter particles annihilate, potentially producing Standard
Constraints on dark matter annihilation and decay from the isotropic gamma-ray background
We study the constraints on dark matter (DM) annihilation/decay from the Fermi-LAT Isotropic Gamma-Ray Background (IGRB) observation. We consider the contributions from both extragalactic and
Search for dark matter signals with Fermi-LAT observation of globular clusters NGC 6388 and M 15
The globular clusters are probably good targets for dark matter (DM) searches in gamma-rays due to the possible adiabatic contraction of DM by baryons. In this work we analyse the three-year data
