“…Including results obtained from other types of observational targets like the Galactic Center, galaxy clusters or others is formally also possible, but a common approach to the J-factor determination remains an open question. In the future, this analysis could include new instruments like CTA [58], GAMMA-400 [59], DAMPE [60] or Km3Net [61]. 13 Our global approach offers the best chances for indirect DM discovery, or for setting the most stringent limits attainable by these kind of observations.…”

We present the first joint analysis of gamma-ray data from the MAGIC Cherenkov telescopes and the Fermi Large Area Telescope (LAT) to search for gamma-ray signals from dark matter annihilation in dwarf satellite galaxies. We combine 158 hours of Segue 1 observations with MAGIC with 6-year observations of 15 dwarf satellite galaxies by the Fermi-LAT. We obtain limits on the annihilation cross-section for dark matter particle masses between 10 GeV and 100 TeV -the widest mass range ever explored by a single gamma-ray analysis. These limits improve on previously published Fermi -LAT and MAGIC results by up to a factor of two at certain masses. Our new inclusive analysis approach is completely generic and can be used to perform a global, sensitivity-optimized dark matter search by combining data from present and future gamma-ray and neutrino detectors.

“…It features a large field-of-view (∼ 2.4 sr) and operates primarily in sky-scanning mode, enabling studies of sources all over the sky, including large-scale diffuse emission. The GAMMA-400 telescope, with a planned launch in 2019, will cover a similar energy range to the LAT but with improved angular and energy resolution [68].…”

The indirect detection of dark matter annihilation and decay using observations of photons, charged cosmic rays, and neutrinos offers a promising means of identifying the particle nature of this elusive component of the universe. The last decade has seen substantial advances in observational data sets, complemented by new insights from numerical simulations, which together have enabled for the first time strong constraints on dark matter particle models, and have revealed several intriguing hints of possible signals. This review provides an introduction to indirect detection methods and an overview of recent results in the field.Comment: 32 pages, 6 figures; invited review, accepted to Contemporary Physic

“…There are currently no planned gamma-ray experiments that would lead to significant improvements on these indirect detection limits in the channels relevant to our models. The Gamma-400 satellite will have significantly better angular and energy resolution than the Fermi-LAT, allowing it to perform very sensitive searches for strong spectral features such as gamma-ray lines [36]. The effective area will be smaller, however, leading to only minor improvements in the limits in the channels relevant to our models [37].…”

MSSM dark matter and a light slepton sector: The incredible bulk

et al. 2014

Recent experimental results from the LHC have placed strong constraints on the masses of colored superpartners. The MSSM parameter space is also constrained by the measurement of the Higgs boson mass, and the requirement that the relic density of lightest neutralinos be consistent with observations. Although large regions of the MSSM parameter space can be excluded by these combined bounds, leptophilic versions of the MSSM can survive these constraints. In this paper we consider a scenario in which the requirements of minimal flavor violation, vanishing CP -violation, and mass universality are relaxed, specifically focusing on scenarios with light sleptons. We find a large region of parameter space, analogous to the original bulk region, for which the lightest neutralino is a thermal relic with an abundance consistent with that of dark matter. We find that these leptophilic models are constrained by measurements of the magnetic and electric dipole moments of the electron and muon, and that these models have interesting signatures at a variety of indirect detection experiments.
