Dark matter particle annihilation or decay can produce monochromatic gamma-ray lines and contribute to the diffuse gamma-ray background. Flux upper limits are presented for gamma-ray spectral lines from 7 to 200 GeV and for the diffuse gamma-ray background from 4.8 GeV to 264 GeV obtained from two years of Fermi Large Area Telescope data integrated over most of the sky. We give cross section upper limits and decay lifetime lower limits for dark matter models that produce gamma-ray lines or… 

Illuminating the 130 GeV gamma line with continuum photons

A bstractThere is evidence for a 130 GeV γ-ray line at the Galactic Center in the Fermi Large Area Telescope data. Dark matter candidates that explain this feature should also annihilate to Standard

Dark Matter Signals in the gamma-ray sky

Detection of gamma rays and cosmic rays from the annihilation or decay of dark matter particles is a promising method for identifying dark matter, understanding its intrinsic properties, and mapping

Remarks on Two Gamma Ray Lines from the Inner Galaxy

Monochromatic gamma-ray lines are thought to be the smoking gun signal of the annihilation or decay of dark matter since they do not suffer from deflection or absorption on galactic scales. A recent

The observation of a gamma-ray line in the cosmic-ray fluxes would be a smoking-gun signature for dark matter annihilation or decay in the Universe. We present an improved search for such signatures

Decaying vs Annihilating Dark Matter in Light of a Tentative Gamma-Ray Line

Recently reported tentative evidence for a gamma-ray line in the Fermi-LAT data is of great potential interest for identifying the nature of dark matter. We compare the implications for decaying and

Search for gamma-ray lines towards galaxy clusters with the Fermi-LAT

We report on a search for monochromatic γ-ray features in the spectra of galaxy clusters observed by the Fermi Large Area Telescope. Galaxy clusters are the largest structures in the Universe that

EVIDENCE FOR INDIRECT DETECTION OF DARK MATTER FROM GALAXY CLUSTERS IN FERMI γ-RAY DATA

Using the Fermi Large Area Telescope (LAT) we search for spectral features in γ-rays coming from regions corresponding to the 18 brightest nearby galaxy clusters determined by the magnitude of their

Spectral Features from Dark Matter Annihilations and Decays in Indirect Searches

In this thesis we study positron and gamma-ray spectral features from dark matter annihilations and decays. Using AMS-02 data we derive for the first time stringent and robust model-independent

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

Nearby clusters and groups of galaxies are potentially bright sources of high-energy gamma-ray emission resulting from the pair-annihilation of dark matter particles. However, no significant

New gamma-ray contributions to supersymmetric dark matter annihilation

We compute the electromagnetic radiative corrections to all leading annihilation processes which may occur in the Galactic dark matter halo, for dark matter in the framework of supersymmetric

A clear Dark Matter gamma ray line generated by the Green-Schwarz mechanism

We study the phenomenology of a UX(1) extension of the Standard Model where the SM particles are not charged under the new abelian group. The Green-Schwarz mechanism insures that the model is anomaly

Dark matter signals from cascade annihilations

A leading interpretation of the electron/positron excesses seen by PAMELA and ATIC is dark matter annihilation in the galactic halo. Depending on the annihilation channel, the electron/positron

We derive robust model-independent bounds on Dark Matter (DM) annihilations and decays from the first year of FERMI ?-ray observations of the whole sky. These bounds only have a mild dependence on
