Nonlocal gravity and gravitational-wave observations

Will Einstein Have the Last Word on Gravity? Gravitational wave observations probe strong-field nonlinear gravity

This is a whitepaper submitted to the 2010 Astronomy Decadal Review process, addressing the potential tests of gravity theory that could be made by observations of gravitational waves in the milliHertz frequency band by the proposed ESA-NASA gravitational wave observatory LISA. A key issue is that observations in this band of binary systems consisting of black holes offer very clean tests with ...

Testing Gravity with Gravitational Wave Source Counts

We show that the gravitational wave source counts distribution can test how gravitational radiation propagates on cosmological scales. This test does not require obtaining redshifts for the sources. If the signal-to-noise ratio (SNR, ρ) from a gravitational wave source is proportional to the strain then it falls as R−1, thus we expect the source counts to follow dN/dρ ∝ ρ−4. However, if gravita...

Constraining the braneworld with gravitational wave observations.

Some braneworld models may have observable consequences that, if detected, would validate a requisite element of string theory. In the infinite Randall-Sundrum model (RS2), the AdS radius of curvature, l, of the extra dimension supports a single bound state of the massless graviton on the brane, thereby reproducing Newtonian gravity in the weak-field limit. However, using the AdS/CFT correspond...
