Extreme Black-Hole Binaries

In this talk I will show recent results obtained by the RIT group from simulations of highly-spinning binaries, including new data that gives near maximal spins, and high-mass ratio binaries. Simulations in both of these regimes are numerically challenging. However, as astrophysical binaries are expected to be highly-spinning and have high mass ratios, accurate simulations in these regimes are crucial for understanding the dynamics of realistic binaries.
