Radiation Outer Boundary Conditions for the Teukolsky equation
Contributed Talk , APS Global Physics Summit 2026 , Denver, Colorado
This talk presents my recent work on radiation outer boundary conditions for the Bardeen-Press equation. This technique helps us to solve the BP equation in the time domain but with a much smaller computational domain. This helps in producing high resolution simulations efficiently, since we can have $\Delta x$ and $\Delta t$ small. Without this technique, a smaller computational domain would lead to spurious reflections from the outer boundary, which can contaminate the true physical solution.
