Title: Constraints on decaying dark matter from the isotropic gamma-ray background

Abstract

If the dark matter is unstable, the decay of these particles throughout the universe and in the halo of the Milky Way could contribute significantly to the isotropic gamma-ray background (IGRB) as measured by Fermi. Here, we calculate the high-latitude gamma-ray flux resulting from dark matter decay for a wide range of channels and masses, including all contributions from inverse Compton scattering and accounting for the production and full evolution of cosmological electromagnetic cascades. We also make use of recent multi-wavelength analyses that constrain the astrophysical contributions to the IGRB, enabling us to more strongly restrict the presence any component arising from decaying dark matter. Lastly, over a wide range of decay channels and masses (from GeV to EeV and above), we derive stringent lower limits on the dark matter's lifetime, generally in the range of τ ~ (1-5)× 10²⁸ s.}

Strong constraints on thermal relic dark matter from Fermi-LAT observations of the Galactic Center

Journal Article Abazajian, Kevork N. ; Horiuchi, Shunsaku ; Kaplinghat, Manoj ; ... - Physical Review D

The extended excess toward the Galactic Center (GC) in gamma rays inferred from Fermi-LAT observations has been interpreted as being due to dark matter (DM) annihilation. Here, we perform new likelihood analyses of the GC and show that, when including templates for the stellar galactic and nuclear bulges, the GC shows no significant detection of a DM annihilation template, even after generous variations in the Galactic diffuse emission models and a wide range of DM halo profiles. We include Galactic diffuse emission models with combinations of three-dimensional inverse Compton maps, variations of interstellar gas maps, and a central source ofmore »« less

Constraints on the Galactic Halo Dark Matter From FERMI-LAT Diffuse Measurements

Journal Article Ackermann, M. ; Ajello, M. ; Atwood, W. B. ; ... - The Astrophysical Journal

For this study, we have performed an analysis of the diffuse gamma-ray emission with the Fermi Large Area Telescope (LAT) in the Milky Way halo region, searching for a signal from dark matter annihilation or decay. In the absence of a robust dark matter signal, constraints are presented. We consider both gamma rays produced directly in the dark matter annihilation/decay and produced by inverse Compton scattering of the e⁺/e^– produced in the annihilation/decay. Conservative limits are derived requiring that the dark matter signal does not exceed the observed diffuse gamma-ray emission. A second set of more stringent limits is derivedmore »« less

Utilizing the Fermi measurement of the γ -ray spectrum toward the Inner Galaxy, we derive some of the strongest constraints to date on the dark matter (DM) lifetime in the mass range from hundreds of MeV to above an EeV. Our profile-likelihood-based analysis relies on 413 weeks of Fermi Pass 8 data from 200 MeV to 2 TeV, along with up-to-date models for diffuse γ -ray emission within the Milky Way. We model Galactic and extragalactic DM decay and include contributions to the DM-induced γ -ray flux resulting from both primarymore »« less

Conservative constraints on dark matter from the Fermi-LAT isotropic diffuse gamma-ray background spectrum

Journal Article Abazajian, Kevork N. ; Agrawal, Prateek ; Chacko, Zackaria ; ... - Journal of Cosmology and Astroparticle Physics

We examine the constraints on final state radiation from Weakly Interacting Massive Particle (WIMP) dark matter candidates annihilating into various standard model final states, as imposed by the measurement of the isotropic diffuse gamma-ray background by the Large Area Telescope aboard the Fermi Gamma-Ray Space Telescope. The expected isotropic diffuse signal from dark matter annihilation has contributions from the local Milky Way (MW) as well as from extragalactic dark matter. The signal from the MW is very insensitive to the adopted dark matter profile of the halos, and dominates the signal from extragalactic halos, which is sensitive to the lowmore »« less
