Speaker: Dr. Katie Breivik (The Center for Computational Astrophysics at the Flatiron Institute) Title: Black hole binary formation: a multi-messenger, multi-band puzzle Abstract: 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 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 black hole binaries. About the speaker: Katie is currently a Flatiron Research Fellow at the Flatiron Institute in New York City. Before that, she spent two years as a CITA Fellow at the Canadian Institute for Theoretical Astrophysics after finishing her PhD in Physics and Astronomy at Northwestern University. Her research focuses on connecting large simulated populations of binary stars to observations from gravitational wave and electromagnetic surveys to infer how different models of binary star evolution are imprinted into observable binary populations. ---------------------------------------------------------------------------------------------------------------------------------- Join Zoom Meeting by clicking the link in the material below or https://zoom.us/j/9952917599?pwd=MHdiOFRIRG1kVFJ2a1JjVXczVEVnUT09 Meeting ID: 995 291 7599 Passcode: PHAS ---------------------------------------------------------------------------------------------------------------------------------- Please also visit Department Colloquia webpage.
