Gravitational Wave Sources:
Backgrounds for space based detectors

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", as well as resolvability of individual coalescence events of massive, compact objects.

Together with Alessandra Buonanno we have looked at noise at milli Hertz frequencies, produced by the inspiral of stellar mass compact objects immersed in accretion disks around supermassive black holes. This could be relevant for space based interferometers such as LISA.
