Abstract
The majoron provides an attractive dark matter candidate, directly associated to the mechanism responsible for spontaneous neutrino mass generation within the standard model framework. Here we update the cosmological and astrophysical constraints on majoron dark matter which come from the Cosmic Microwave Background (CMB) and a variety of X- and gamma-ray observations.
