The Multi-parameter Test of Gravitational Wave Dispersion with Principal Component Analysis
The Multi-parameter Test of Gravitational Wave Dispersion with Principal Component Analysis
Abstract In this work, we consider a conventional test of gravitational wave (GW) propagation which is based on the phenomenological parameterized dispersion relation to describe potential departures from General Relativity (GR) along the propagation of GWs. But different from tests conventionally performed previously, we vary multiple deformation coefficients simultaneously and …
