The international consortium of other pulsar timing array consortia. Currently it is composed of the European Pulsar Timing Array (EPTA), the Parkes Pulsar Timing Array (PPTA), and NANOGrav. We are working towards a new framework to include the Chinese Pulsar Timing Array (CPTA), the Indian Pulsar Timing Array (InPTA), and a South African Pulsar Timing Array via MeerKAT.
