Parkes Pulsar Timing Array

(group of pulsars timed by Parkes Observatory)

Parkes Pulsar Timing Array (PPTA) is a pulsar timing array, a selected group of pulsars, and an effort to record the timing of the pulsars' cycles using the Parkes Observatory in New South Wales and to compare and analyze their timing histories to detect gravitational waves. It is part of the International Pulsar Timing Array.

The array consists of more than twenty pulsars. The term PPTA4 refers to a subset of four millisecond pulsars specifically chosen for study because a very high-precision timing history has been obtained for them.
