This Project aims to detect ripples in the fabric of spacetime known as gravitational waves through innovative new data analysis techniques while developing technology to enable the next generation of gravitational-wave
detectors. Detection of gravitational waves will constitute a revolution in astronomy, allowing us to probe the most
dramatic events in the Universe with a new form of radiation. During the next five years, it is probable that gravitational waves will be detected. Terrestrial detectors, operating in the audio band, and pulsar timing arrays, operating in the nanohertz band, are both rapidly approaching the required sensitivity. This Project makes important contributions to gravitational-wave astronomy at a crucial time.
