Probing extra dimensions with gravitational waves

Abstract:

I will discuss possibility to use the propagating gravitational waves as a tool to probe the extra dimensions. The focus will be made on 5-dimensional space-time with non-gravitational physics resigning on the 4-dimensional subspace (brane). Few interesting effects will be discussed: a tail effect for a signal of finite duration, screening at the forefront of this signal and a frequency-dependent amplification for a periodic signal.
