Journal ArticleDOI

Introducing the CTA concept

B. S. Acharya, +982 more
TL;DR: The Cherenkov Telescope Array (CTA) as discussed by the authors is a very high-energy (VHE) gamma ray observatory with an international collaboration with more than 1000 members from 27 countries in Europe, Asia, Africa and North and South America.
Journal ArticleDOI

Fermi LAT Search for Internal Bremsstrahlung Signatures from Dark Matter Annihilation

TL;DR: In this article, a new adaptive procedure was proposed to select optimal target regions that takes into account both standard and contracted dark matter profiles, with a significance of 3.1σ (4.3σ) for an internal bremsstrahlung-like signal that would correspond to a dark matter mass of ~150 GeV.
Journal ArticleDOI

New gamma-ray contributions to supersymmetric dark matter annihilation

TL;DR: In this paper, 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 extensions of the Standard Model (MSSM) and mSUGRA, were presented.
Journal ArticleDOI

New positron spectral features from supersymmetric dark matter: A way to explain the PAMELA data?

TL;DR: In this paper, the same type of corrections can also lead to sizeable enhancements in the positron yield, albeit for a smaller region of parameter space than for gammarays; selecting models with a small mass difference between the neutralino and sleptons, the effect becomes more pronounced.
Journal ArticleDOI

Particle models and the small-scale structure of dark matter

TL;DR: The kinetic decoupling of weakly interacting massive particles (WIMPs) in the early universe sets a scale that can directly be translated into a small-scale cutoff in the spectrum of matter density fluctuations.
