Compact binary systems in the post-Newtonian limit of gravitational theories with preferred frames
Oliver Pitt, Timothy Clifton
Gravitational-wave observations of compact-binary inspirals offer the opportunity to test deviations from general relativity in both strong and weak-field regimes. In previous work…

Post-Newtonian Global Conservation Laws in the Presence of Sensitive Bodies
Timothy Clifton, Asta Heinesen, Oliver Pitt
The parameterized post-Newtonian (PPN) approach is the state of the art formalism for performing theory independent tests of weak-field gravity, and for constraining possible devia…

Constraining the Cosmological Evolution of Post-Newtonian Parameters with Gravitational Wave Signals from Compact Binary Inspirals
Oliver Pitt, Timothy Clifton
Gravitational waves from compact binary inspirals offer a new opportunity to constrain the cosmological time dependence of gravitational coupling parameters, due to the high precis…
