Gravitational Wave Sources:
Astrophysical Sources for ground based interferometers

I have recently become interested in astrophysical sources of gravitational waves, and in particular in the diffuse background "noise" they can give rise to. Interesting questions there concern the statistical character of these backgrounds, such as "gaussian", "popcorn", and "adiabatic" noises and their "duty cycles".

Together with Alessandra Buonanno and collaborators from Munich we have looked at low frequency (Hz range) noise from the gravitational memory effect of anisotropic emission of neutrinos from type II supernovae. This could be relevant for projects such as the Big Bang observatory (BBO) or, in extreme cases involving a strong population III star component, for ground based interferometers.
