Improving timing precision of millisecond pulsars using polarization Pulsar timing enables the most stringent tests of fundamental physics. By monitoring the pulse times of arrival (ToAs) of an ensemble of stable millisecond pulsars (MSPs), known as a pulsar timing array (PTA), it is possible to detect nanohertz gravitational waves (GWs). The success of GW detection with PTAs requires the highest possible timing precision.
