| Popis: | We propose that photons produced by decaying particles may account for the recently observed isotropic infrared background (IRB) between 1 and 5 μm. We find that for decaying particle masses mx between 5 and 18 keV, lifetime τd between 2 and 7 × 1010 s, and photon branching ratio Bγ between 4 and 9 × 10−4, the observed spectrum of decay photons is consistent with the observed spectrum of the IRB. The same parameters can explain the submillimeter background. |
