Gravitational wave science in the next decade: a new frontier for numerical relativity.

The newly upgraded LIGO and Virgo observatories are regularly detecting gravitational waves from merging black holes and neutron stars, with public alerts for candidate events coming at a rate of about one per day. These observations provide new information about the population of black holes in the near universe, giving clues about their formation and history, and they allow us to test general relativity as a theory of gravity. While numerical relativity waveforms are essential for gravitational wave analysis, they are computationally expensive and time consuming to compute, taxing the capabilities of our current resources. I will talk about our work to speed up these calculations using new computational methods, such as wavelet-based refinement and innovative differencing techniques. I will also discuss the challenge posed by the next generation of gravitational wave detectors, such as LISA. These detectors will see a wider range of sources, for longer times, and with significantly better precision. With numerical relativity pushing the limits of today's computers, we will need new approaches in the next decade of gravitational wave science.
