Pulsar kicks induced by spin flavour oscillations of neutrinos in gravitational fields

The origin of pulsar kicks is reviewed in the framework of the spin-flip conversion of neutrinos propagating in the gravitational field of a magnetized protoneutron star. We find that for a mass in rotation with angular velocity ω, the spin connections entering in the Dirac equation give rise to the coupling term ω×p, where p is the neutrino momentum. Such a coupling can be...

Microlensing search towards M 31

We present the first results of the analysis of data collected during the 1998–99 observational campaign at the 1.3 meter McGraw-Hill Telescope, towards the Andromeda galaxy (M 31), aimed to detect gravitational microlensing effects as a probe for the presence of dark matter in our Galaxy and in the M 31 halo. The analysis is performed using the pixel lensing technique, which...
