Numerical relativity and simulating merging compact object binaries with very different masses

The intersection of general relativity and computational physics has provided important theoretical input for the recent detection of gravitational waves. Indeed, numerical relativity is likely to continue providing important insights to the emerging field of gravitational wave astronomy. We will review some of this work together with some of the computational ingredients necessary to simulate sources of gravitational radiation; one example being binary compact objects of roughly equal mass. We will also describe some current work and some of the additional computational elements needed to simulate binaries of very different mass ratios.
