Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

Abstract

We consider the scattering of neutrinos and gravitational waves produced in supernovae (SN) explosions. Nonlinear scattering processes lead to absorption of neutrinos by the dense plasma surrounding the core, and may contribute to reviving the stalled shock wave. We estimate that about 1–10% of the neutrino energy may be absorbed by the plasma. A formalism is also presented which describes neutrino oscillations into different flavours using mode conversion techniques developed for fluids. Scattering of gravitational waves is also a possibility which may be important in the propagation and absorption of gravitational radiation. This scattering may change the expected waveform signal of gravitational waves.
