Polarization of gravitational waves in modified gravity

M Khlopov, SR Chowdhury - Symmetry, 2023 - mdpi.com
An investigation has been carried out on a reconfigured form of the Einstein-Hilbert action,
denoted by f (R, T ϕ), where T ϕ represents the energy-momentum tensor trace of the scalar …

Scalar mode quadrupole radiation from astronomical sources in modified gravity

T Inagaki, M Taniguchi - Physical Review D, 2023 - APS
We investigate the scalar mode quadrupole radiation of gravitational waves in F (R)
modified gravity. In F (R) gravity a massive scalar mode appears in the gravitational waves …
