Constraints on parameters of radiatively decaying dark matter from the galaxy cluster 1E0657-56
We derived constraints on parameters of a radiatively decaying warm dark matter particle, e.g., the mass and mixing angle for a sterile neutrino, using Chandra X-ray spectra of a galaxy cluster 1E0657-56 (the ``bullet'' cluster). The constraints are based on nondetection of the sterile neu...
