A Robust Approach to Constraining Dark Matter from Gamma-Ray Data

Journal Article Baxter, Eric J ; /Chicago U., Astron. Astrophys. Ctr. ; Dodelson, Scott ; ... - Phys.Rev.D83:123516,2011

Photons produced in the annihilations of dark matter particles can be detected by gamma-ray telescopes; this technique of indirect detection serves as a cornerstone of the upcoming assault on the dark matter paradigm. The main obstacle to the extraction of information about dark matter from the annihilation photons is the presence of large and uncertain gamma-ray backgrounds. We present a new technique for using gamma-ray data to constrain the properties of dark matter that makes minimal assumptions about the dark matter and the backgrounds. The technique relies on two properties of the expected signal from annihilations of the smooth darkmore »« less

Annihilation vs. decay: constraining dark matter properties from a gamma-ray detection

Journal Article Palomares-Ruiz, Sergio ; Siegal-Gaskins, Jennifer M., E-mail: sergio.palomares.ruiz@ist.utl.pt, E-mail: jsg@mps.ohio-state.edu - Journal of Cosmology and Astroparticle Physics

Most proposed dark matter candidates are stable and are produced thermally in the early Universe. However, there is also the possibility of unstable (but long-lived) dark matter, produced thermally or otherwise. We propose a strategy to distinguish between dark matter annihilation and/or decay in the case that a clear signal is detected in gamma-ray observations of Milky Way dwarf spheroidal galaxies with gamma-ray experiments. The sole measurement of the energy spectrum of an indirect signal would render the discrimination between these cases impossible. We show that by examining the dependence of the intensity and energy spectrum on the angular distributionmore »« less

A model-independent analysis of the Fermi Large Area Telescope gamma-ray data from the Milky Way dwarf galaxies and halo to constrain dark matter scenarios

Journal Article Mazziotta, M. N. ; Loparco, F. ; de Palma, F. ; ... - Astroparticle Physics

Here, we implemented a novel technique to perform the collective spectral analysis of sets of multiple gamma-ray point sources using the data collected by the Large Area Telescope onboard the Fermi satellite. The energy spectra of the sources are reconstructed starting from the photon counts and without assuming any spectral model for both the sources and the background. In case of faint sources, upper limits on their fluxes are evaluated with a Bayesian approach. Our analysis technique is very useful when several sources with similar spectral features are studied, such as sources of gamma rays from annihilation of dark mattermore »« less

Constraining cosmological dark matter annihilation with gamma ray observations

Annihilation of cosmologically distributed dark matter is predicted to produce a potentially observable flux of high energy photons. This signal is predicted to be virtually uniform on the sky but, in order to be identified, must be extracted from various galactic and extragalactic backgrounds. We consider three techniques for extracting this signal from the backgrounds: spectral discrimination, angular discrimination, and distribution discrimination. We analyze the first two of these with the Fisher matrix formalism to obtain projections for constraints from the Fermi satellite. The third technique exploits the fact that the number of photons from extragalactic blazars is drawn frommore »« less
