Meeting Challenges at the Next Frontier in Numerical Relativity

Numerical relativity has been a frontier problem in computational science for over fifty years. As gravitational wave detectors continually improve, and new detectors come online, a new challenge will be to compute waveforms with higher fidelity and for a broader array of possible sources. I will talk about some of the recent work in numerical relativity to model binary black holes for gravitational wave analysis. We have developed Dendro-GR, a new computational platform for numerical relativity that uses a highly scalable octree with sparse, wavelet-based refinement. I will present some of initial results obtained with Dendro-GR for merging black hole binaries with different mass ratios.
