DOIAbstract
The International Pulsar Timing Array project combines observations of pulsars from both northern and southern hemisphere observatories with the main aim of detecting ultra-low frequency (similar to 10(-9)-10(-8) Hz) gravitational waves. Here we introduce the project, review the methods used to search for gravitational waves emitted from coalescing supermassive binary black-hole systems in the centres of merging galaxies and discuss the status of the project.Astronomy & AstrophysicsPhysics, MultidisciplinaryPhysics, Particles & FieldsSCI(E)CPCI-S(ISTP)13
