Black hole formation: a multi-wavelength, multi-messenger puzzle

Recent observations of binary black hole and binary neutron star mergers have ignited interest in the formation and evolution of compact-object binary 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 the 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 an openly developed population synthesis code: COSMIC and highlight recent work which explores how to combine binary population simulations with current and future data from gravitational wave and electromagnetic surveys to constrain the formation and evolution of black hole binaries.
