Description
The pulsar timing arrays' recent astronomical milestone of the detection of the stochastic gravitational wave background presents a new window of opportunity to study gravity in the nanohertz gravitational wave regime. In this talk, we present such tests focusing on both pulsar timing array measurements of the gravitational wave spatial correlation and the power spectrum. Our results suggest that PTAs can be its best version for testing gravity by focusing on the power spectrum.
