Measuring the Modified Gravitational Wave Propagation beyond General Relativity from CMB Observations

In modified gravity theories, gravitational wave propagations are presented in nonstandard ways. We consider a friction term different from GR and constrain the modified gravitational waves propagation from observations. The modified gravitational waves produce anisotropies and polarization, which g...
