Edward Fomalont (born May 14, 1940) is an American scientist working at the National Radio Astronomy Observatory.
He specializes in radio galaxies, X-ray binary systems, astrometry, and general relativity.
[1] In 1975, Fomalont and Richard Sramek made a first radio-interferometric occultation experiment to test the theory of general relativity by measuring the bending of microwave radiation in the gravitational field of the Sun.
[3] In 2002, Fomalont and Sergei Kopeikin claimed to have measured the speed of gravity in the dedicated experiment[4][5] by observing the tangential component in the gravitational bending of light of a quasar caused by the orbital motion of Jupiter with respect to the barycenter of the solar system.
[8][9][10] Fomalont is an active participant in many international radio interferometric projects including the VLBI Space Observatory Programme and Square Kilometre Array.
