This award supports research in relativity and relativistic astrophysics, and it addresses the priority areas of NSF's "Windows on the Universe" Big Idea. Gravitational waves are ripples in the fabric of spacetime caused by the violent acceleration of extremely compact objects, like black holes and neutron stars smashing together billions of light-years away, or exotic processes in the very early universe. Detecting…
