Popis:	Complementary to ground-based laser interferometers, pulsar timing array experiments are being carried out to search for nanohertz gravitational waves. Using the world's most powerful radio telescopes, three major international collaborations have collected $\sim$10-year high precision timing data for tens of millisecond pulsars. In this paper we give an overview on pulsar timing experiments, gravitational wave detection in the nanohertz regime, and recent results obtained by various timing array projects. Comment: 11 pages, 5 figures, review article for the special issue of SCIENCE CHINA Physics, Mechanics & Astronomy to mark the Centenary of General Relativity
