The LISA Astrophysics Working Group held a hybrid meeting the week of June 20th with a focus on LISA multimessenger science, as well as theoretical and observational work needed in the years before the mission launch to best support LISA science during observations. Tyson Littenberg (ST13) participated in project planning sessions with the goal of quantitatively comparing population synthesis simulations of ultra-compact binaries in our Galaxy both in terms of current electromagnetically known populations and LISA observables. Three concrete projects (short, medium, and long term) were formulated and the MSFC gravitational wave group will support simulation of the LISA observations for each. Littenberg also provided a progress report on the LISA Consortium's data simulation and pipeline development.
