Abstract:

Recent observations of gravitational waves from merging double-compact-object binaries have reignited an explosive interest in the formation and evolution of compact objects in binary-star systems. However, by the time a compact-object binary merges and produces the gravitational-wave signals we observe, much of the evolutionary history of the system is washed away. By combining binary population synthesis simulations with gravitational-wave and electromagnetic observations, we can constrain uncertain processes that govern the evolution of binary stars from their birth through to compact object formation and merger. In this talk I will introduce a community developed population synthesis code: COSMIC and highlight recent work which explores ways to combine binary population simulations with current and future data from gravitational wave and electromagnetic surveys to constrain the formation and evolution of binary-star populations.
