Description
Recently two groups have reported an unidentified line-like feature in the
X-ray spectra of dark matter-dominated objects (galaxies and galaxy
clusters) [Bulbul et al.][1] and [Boyarsky et al.][2]. We discuss the signal and consistency of its interpretation in
terms of dark matter decay.
