On the frequency of gravitational waves
Chiara Caprini, Ruth Durrer, Riccardo Sturani
We show that there are physically relevant situations where gravitational waves do not inherit the frequency spectrum of their source but its wavenumber spectrum.

No-go theorem for k-essence dark energy
Camille Bonvin, Chiara Caprini, Ruth Durrer
We demonstrate that if k-essence can solve the coincidence problem and play the role of dark energy in the universe, the fluctuations of the field have to propagate superluminally…

Gravitational waves from stochastic relativistic sources: primordial turbulence and magnetic fields
Chiara Caprini, Ruth Durrer
The power spectrum of a homogeneous and isotropic stochastic variable, characterized by a finite correlation length, does in general not vanish on scales larger than the correlatio…
