The contributions of the decay of supersymmetry-breaking photinos and gravitinos with masses of a few keV to the X-ray background and of neutrinos with mass about 20 eV to the UV background are discussed, using the Coma ...

The effects of uncertainties in determining the loss of neutrinos and the generation of entropy during the collapse of a stellar core are studied using a simple spherically-symmetric homologous collapse model with an ...

We consider the Čerenkov radiation emitted by neutrinos due to their effective electromagnetic interactions as they pass through a polarisable medium. The effect exists even for massless, chiral neutrinos, and no physics ...

Recently it was pointed out that a non-zero cosmological constant can play a role in the formation of neutrino halos only in the case of neutrinos of very low rest mass (mν ≤ 0.1 eV). However, phase-space considerations ...
