Journal ArticleDOI
Simplified dark matter models for the Galactic Center gamma-ray excess
TL;DR: In this paper, the authors revisited models in which the dark matter interacts with the Standard Model through the exchange of a new neutral gauge boson, and found several scenarios that can account for this signal, while respecting all existing constraints from colliders and direct-detection experiments.
Journal ArticleDOI
Severely Constraining Dark-Matter Interpretations of the 21-cm Anomaly
TL;DR: This Letter explores the possibility that the gas in the early Universe was cooled during this era as a result of scattering with dark matter, applying constraints from the cosmic microwave background, light element abundances, Supernova 1987A, and a variety of laboratory experiments.
Journal ArticleDOI
Constraining Light Dark Matter with Diffuse X-Ray and Gamma-Ray Observations
Rouven Essig,Eric Kuflik,Samuel D. McDermott,Samuel D. McDermott,Tomer Volansky,Kathryn M. Zurek +5 more
TL;DR: In this article, the authors present constraints on decaying and annihilating dark matter (DM) in the 4 keV to 10 GeV mass range, using published results from the satellites HEAO-1, INTEGRAL, COMPTEL, EGRET and Fermi Gamma-ray Space Telescope.
Journal ArticleDOI
Constraints on Scalar Asymmetric Dark Matter from Black Hole Formation in Neutron Stars
TL;DR: In this article, the authors consider the effects of asymmetric dark matter (ADM) in neutron stars and find that the constraint from nearby neutron stars on the scattering cross-section with neutrons ranges from √ √ n √ 2 to √ 10 √ 6 √ 3 √ 4 √ 5 √ 13 GeV.
Journal ArticleDOI
Turning off the lights: How dark is dark matter?
TL;DR: In this article, the authors consider current observational constraints on the electromagnetic charge of dark matter and show that charged dark matter particles are likely to be evacuated from the Galactic disk by the Galactic magnetic fields and supernova shock waves and hence will not give rise to a signal.
