We calculate the bounds which could be placed on scalar-tensor theories of gravity of the Jordan, Fierz, Brans and Dicke type by measurements of gravitational waveforms from neutron stars (NS) spiraling into massive black holes (MBH) using LISA, the proposed space laser interferometric observatory. Such observations may yield significantly more stringent bounds on the Brans-Dicke coupling parameter $\ensuremath{\omega}$ than are achievable from solar system or binary pulsar measurements. For NS…

Testing alternative theories of gravity using LISA

We investigate the possible bounds which could be placed on alternative theories of gravity using gravitational wave detection from inspiralling compact binaries with the proposed LISA space

Constraining Screened Modified Gravity with Spaceborne Gravitational-wave Detectors

Screened modified gravity (SMG) is a unified theoretical framework that describes scalar–tensor gravity with a screening mechanism. Based on the gravitational-wave (GW) waveform derived in our

Sensitivity Analysis of a Space-borne Gravitational Wave Detector

Abstract : Modern theories of gravity predict ripples in space and time, which are known as gravitational waves. Very large interacting masses, such as binary systems of neutron stars or black holes,

Testing gravity with gravitational waves from binary black hole mergers: Contributions from amplitude corrections

The detection of gravitational waves has offered us the opportunity to explore the dynamical and strong-field regime of gravity. Because matched filtering is more sensitive to variations in the

Gravitational waveforms in scalar-tensor gravity at 2PN relative order

We compute the gravitational waveform from a binary system in scalar-tensor gravity at 2PN relative order. We restrict our calculation to non-spinning binary systems on quasi-circular orbits and

Gravitational wave emission under general parametrized metric from extreme mass ratio inspirals

Future space-borne interferometers will be able to detect gravitational waves at $10^{-3}$ to $10^{-1}$ Hz. At this band extreme-mass-ratio inspirals (EMRIs) can be promising gravitational wave

The observations of gravitational-wave signals from astrophysical sources such as binary inspirals will be used to test General Relativity for self consistency and against alternative theories of

Observations of binary inspirals with the proposed Laser Interferometer Space Antenna (LISA) will allow us to place bounds on alternative theories of gravity and to study the merger history of
