Precision Astrometry Using Optically Independent Spacecraft for Graviational Wave Detection

The Brookhaven National Laboratory’s team is pursuing a novel strategy for detecting gravitational waves at lower frequencies utilizing an astrometry-based technique. This innovative methodology hinges on identifying the subtle, correlated movement of celestial bodies caused by passing gravitational waves. Specifically, researchers aim to observe the coordinated apparent motion of all sky objects resulting from gravitational wave passage. A key element involves deploying optically independent spacecraft to achieve this precise measurement. Initial efforts focus on developing this new approach to enhance sensitivity in gravitational wave detection experiments.
