Astrophysics research at CGWA involves modeling populations of compact object binaries in the Galaxy and its environs in order to determine how gravitational wave observations can shed light on models of stellar evolution and Galactic structure. This research is relevant to gravitational wave observations using LIGO, LISA, and Pulsar Timing Arrays (PTA) including NANOGrav. CGWA is a member of the Transient Optical Robotic Observatory of the South (TOROS) collaboration, created to search for kilonova associated with the merger of neutron stars.
