Topic Low-Frequency Gravitational Waves Gravitational waves are ripples in space-time predicted by Einstein's theory of general relativity. They are produced by accelerating masses and can be used to study objects like black hole binaries which do not emit visible light. Our experiment is sensitive to low-frequency gravitational waves with periods of years to decades. Topic Galaxies and Supermassive Black Holes Galaxies have evolved through cosmic time through consecutive mergers with other galaxies. We will gain unique insights into this important process by detecting the gravitational waves produced by extremely massive pairs of black holes at the cores of merged galaxies. Topic Pulsars as Cosmic Clocks Neutron stars are the collapsed cores of massive stars which have ended their lives in cataclysmic supernova explosions. Pulsars are rapidly rotating, highly magnetic neutron stars which emit beamed radio emission, like cosmic lighthouses. They are unique laboratories for a variety of fundamental physics experiments. Topic Radio Astronomy We observe with the largest telescopes in the world in order to detect electromagnetic waves with the very longest wavelengths. Radio astronomy allows us to probe energetic processes which are invisible to optical telescopes. Topic 15-Year Publications' Summaries PreviousNext See All Science Topics Collaboration Our goal is to detect low-frequency gravitational waves and use our measurements to characterize the low-frequency gravitational wave universe. Our pulsar timing observations also allow a wealth of other astrophysical experiments and applications.
