Strong Equivalence Principle and Gravitational Wave Polarizations in Horndeski Theory
Shaoqi Hou, Yungui Gong
The relative acceleration between two nearby particles moving along accelerated trajectories is studied, which generalizes the geodesic deviation equation. The polarization content…
Gravitational waves in Einstein-Æther theory and generalized TeVeS theory after GW170817
Shaoqi Hou, Yungui Gong
In this paper, the polarization contents of Einstein-æther theory and the generalized TeVeS theory are studied. The Einstein-æther theory has five polarizations, while the generali…
Gravitational waves and the polarizations in Hořava gravity after GW170817
Yungui Gong, Shaoqi Hou, Eleftherios Papantonopoulos +1
The gravitational waves of Hořava gravity, their polarization states and their possible observational signatures are discussed. Using the gauge-invariant variable formalism, we fou…
The Polarizations of Gravitational Waves
Yungui Gong, Shaoqi Hou
The direct detection of gravitational waves by LIGO/Virgo opened the possibility to test General Relativity and its alternatives in the high speed, strong field regime. Alternative…
Gravitational waves in Einstein-æther and generalized TeVeS theory after GW170817
Yungui Gong, Shaoqi Hou, Dicong Liang +1
In this work, we discuss the polarization contents of Einstein-æther theory and the generalized tensor-vector-scalar (TeVeS) theory, as both theories have a normalized timelike vec…
