International Pulsar Timing Array

(organization of pulsar timing arrays)

The International Pulsar Timing Array (IPTA) is a consortium of pulsar timing arrays, aimed at using pulsar timing observations to detect gravitational waves. The gist of the effort is the group's collection and analysis of pulsar timing data, using select data (based upon the precision and accuracy) from that of the Parkes Pulsar Timing Array, the European Pulsar Timing Array, and NANOGrav and other sources.

PTAs as GW detectors are sensitive to a different range of frequencies than LIGO and Virgo: rather than the 10-10000 Hz region, its range is in mHz or slower, the presumed sources being supermassive black hole mergers.

IPTA+ is this set of data, combined with a bit more data, once again selected on the basis of the precision and accuracy of the timing.
