Constraints on dark matter annihilation from M87: Signatures of prompt and inverse-Compton gamma rays
Sheetal Saxena, Alexander Summa, Dominik Elsässer +2
As the largest mass concentrations in the local Universe, nearby clusters of galaxies and their central galaxies are prime targets in searching for indirect signatures of dark matt…
Ancient Pulsar Wind Nebulae in light of recent GeV and TeV observations
O. Tibolla, K. Mannheim, D. Elsässer +1
In a Pulsar Wind Nebula (PWN), the lifetime of inverse Compton emitting electrons exceeds the lifetime of its progenitor pulsar, but it exceeds also the age of the electrons that e…
Dark matter subhaloes as gamma-ray sources and candidates in the first Fermi-LAT catalogue
H. -S. Zechlin, M. V. Fernandes, D. Elsaesser +1
The standard paradigm of hierarchical structure formation in a LambdaCDM universe predicts the presence of dark matter subhaloes, hosted by Milky Way-sized galaxies. Anticipated su…
New developments in the ancient PulsarWind Nebulae scenario
O. Tibolla, K. Mannheim, S. Kaufmann +1
In a Pulsar Wind Nebula (PWN), the lifetime of inverse Compton emitting electrons exceeds the lifetime of its progenitor pulsar, but it exceeds also the age of the electrons that e…
GRIPS - Gamma-Ray Imaging, Polarimetry and Spectroscopy
J. Greiner, K. Mannheim, F. Aharonian +65
We propose to perform a continuously scanning all-sky survey from 200 keV to 80 MeV achieving a sensitivity which is better by a factor of 40 or more compared to the previous missi…
