Constraints on the RP sterile neutrino parameter space from our method are represented as exclusion regions, with 3-σ and 2-σ limits represented by darker and lighter colors. Our constraints are compared with upper bounds from X-ray observations (as reported in Riemer-Sorensen 2016) of the Milky Way and dwarf galaxies. Gray areas are excluded by current limits on the abundance of DM (Ade et al. 2016). The green line corresponds to the non-resonant DW case with vanishing lepton asymmetry L = 0. We also show as a dashed line the constraint obtained in Schneider (2016) from the abundance of satellites in the Milky Way. The tentative line signal at 7.1 keV (Boyarsky et al. 2014; Bulbul et al. 2014) is shown by the point with errorbars.
