Gravitational Waves Propagation through the Stochastic Background of Gravitational Waves

Detecting the Cosmological Stochastic Background of Gravitational Waves with FastICA

We show that the stochastic background of gravitational waves, produced in the early cosmological epochs, strictly depends on the assumed theory of gravity. In particular, the specific form of the function f(R), where R is the Ricci scalar, is related to the evolution and the production mechanism of gravitational waves. Using a neural network algorithm which only requires non-Gaussian nature an...

Stochastic backgrounds of gravitational waves

We review the motivations for the search of stochastic backgrounds of gravitational waves and we compare the experimental sensitivities that can be reached in the near future with the existing bounds and with the theoretical predictions.

Stochastic background of gravitational waves ”tuned” by f(R) gravity

Upper limits on a stochastic background of gravitational waves.

The Laser Interferometer Gravitational-Wave Observatory has performed a third science run with much improved sensitivities of all three interferometers. We present an analysis of approximately 200 hours of data acquired during this run, used to search for a stochastic background of gravitational radiation. We place upper bounds on the energy density stored as gravitational radiation for three d...

Detecting a stochastic background of scalar gravitational waves with LIGO

With the “bouncing photon” treatment, the gauge invariance of the response function of interferometers to scalar gravitational waves (SGWs) has been recently demonstrated in its full frequency dependence in three different gauges well known in literature, while in previous works such invariance was only proved in the low frequencies approximation. After a review of scalar tensor theories of gra...
