Gravitational Waves in Scalar-Tensor-Vector Gravity Theory

Understand

In this paper, we study the properties of gravitational waves in the scalar-tensor-vector gravity theory.

• The polarizations of the gravitational waves are investigated by analyzing the relative motion of the test particles.
• It is found that the interaction between the matter and vector field in the theory leads to two additional transverse polarization modes.
• By making use of the polarization content, the stress-energy pseudo-tensor is calculated by employing the perturbed equation method.
