The University of Massachusetts Dartmouth (UMass Dartmouth) was awarded a $349,101 Project Grant from the National Science Foundation (NSF) Division of Mathematical Sciences under the Mathematical and Physical Sciences program (CFDA 47.049).

The grant will support UMass Dartmouth's development of advanced computational techniques to accurately simulate gravitational waveforms over long time periods. Key activities include developing efficient and stable high-order numerical methods to handle singular source terms in binary black hole simulations. The university will create a novel discontinuous Galerkin scheme and a mixed precision weighted essentially non-oscillatory method. Additionally, UMass Dartmouth will focus on developing high-order, positivity-preserving time-stepping approaches to enhance simulation accuracy. The research aims to model highly realistic astrophysical scenarios involving rapidly spinning black holes that were previously infeasible. The computational skills and research outcomes will significantly impact gravitational wave discoveries enabled by LIGO and future space-based detectors.
