Constraining Gravitational Wave Polarization with GW190521 and ZTF19abanrhr.

HASTER C.-J.

Abstract (from CDS):

Gravitational waves (GWs) in general relativity are assumed to contain only tensorial polarization states, with generic metric theories of gravity also allowing for vector- and scalar-polarized GWs. Assuming an association between the gravitational-wave and electromagnetic transients GW190521 and ZTF19abanrhr, we find a preference for tensorial GWs with a log10 Bayes factor of 21.6 (with respect to vector-polarized GWs) and 38.4 (with respect to scalar-polarized GWs).
