Description
Low-frequency gravitational waves cannot be detected with ground-based detectors.
While GW observations at frequencies in the micro- to mHz regime are planned with
spaced-based detectors, even lower frequencies, such as at nHz frequencies, can be
detected with pulsar timing arrays (PTAs). The talk summarises the PTA experiments,
describes the current status and prospects, and also indicates how gravity tests are
enable by detections.
