TL;DR: The contribution of pulsars to the cosmic ray positron and electron spectra from PAMELA was investigated in this paper, where it was shown that a significant contribution is expected from the sum of all mature pulsars throughout the Milky Way, as well as from the most nearby mature pulsARS (such as Geminga and B0656+14) and that the signal from nearby pulsars is expected to generate a small but significant dipole anisotropy in the Cosmic Ray electron spectrum.

TL;DR: It is found that the possibility that the recent detection of 511 keV gamma rays from the galactic bulge, as observed by INTEGRAL, is a consequence of low mass particle dark matter annihilations is consistent with the observed dark matter relic density and other constraints from astrophysics and particle physics.

TL;DR: In this paper, the authors review the phenomenology of models with flat, compactified extra dimensions where all of the Standard Model fields are allowed to propagate in the bulk, known as Universal Extra Dimensions (UED).

TL;DR: In this article, it was shown that the detectable signature of maverick dark matter is an excess over standard-model expectations of events consisting of large missing transverse energy, together with large leading jet transverse momentum and scalar sum of the transverse momenta of the jets.

TL;DR: In this article, the authors study the variation of the spectrum of the Fermi Bubbles with Galactic latitude and conclude that a second (noninverse-Compton) emission mechanism must be responsible for the bulk of the low-energy, low-latitude emission.
