Decaying dark matter: the case for a deep X-ray observation of Draco
Decaying dark matter: the case for a deep X-ray observation of Draco
Recent studies of M31, the Galactic Centre (GC), and galaxy clusters have made tentative detections of an X-ray line at ∼3.5 keV that could be produced by decaying dark matter. We use high-resolution simulations of the Aquarius project to predict the likely amplitude of the X-ray decay flux observed in …
