Comment on Neutrino Radiative Decay Limits from the Infrared Background

Astrophysics 2009-10-30 v1

Abstract

Recent observations of TeV gamma rays from distant sources provide new limits on the cosmic infrared background and thus on radiative decays of background neutrinos. I translate these limits into bounds on transition dipole moments and compare them with limits from the energy-loss of globular-cluster stars. The latter are more restrictive for neutrino masses below 1-2 eV.
