Updated Parameters for the Decaying Neutrino Theory and EURD Observations of the Diffuse UV Background

D. W. Sciama

Various recent observational developments are here used to make a more critical analysis of the parameter space of the decaying neutrino theory for the ionisation of the interstell…

Decaying Neutrinos and the Flattening of the Galactic Halo

D. W. Sciama

The recently constructed Dehnen-Binney set of mass models for the Galaxy is used to show that the decaying neutrino theory for the ionisation of the interstellar medium (Sciama 199…

An updated precision estimate of the Hubble constant and the age and density of the Universe in the decaying neutrino theory

D. W. Sciama

We here update the derivation of precise values for the Hubble constant H_0, the age t_0 and the density parameter Omega*h^2 of the universe in the decaying neutrino theory for the…

On the Ionisation of Warm Opaque Interstellar Clouds and the Intercloud Medium

D. W. Sciama

In this paper we use a number of observations to construct an integrated picture of the ionisation in the interiors of quiescent warm opaque interstellar clouds and in the interclo…

Resonant spin-flavour precession of neutrinos and pulsar velocities

E. Kh. Akhmedov, A. Lanza, D. W. Sciama

Young pulsars are known to exhibit large space velocities, up to km/s. We propose a new mechanism for the generation of these large velocities based on an asymmetric emissio…
