Calculating gravitational waves at infinity: the missing link
Gravitational-wave science requires waveform templates to be computed at future null infinity, the asymptotic boundary of spacetime. Numerical solutions ...
Accurate initial data for Cauchy-characteristic evolution
Accurate gravitational-wave (GW) templates from numerical-relativity (NR) simulations are essential for GW science. These templates are typically compute...
NRSur7dq4v2: A multi-domain precessing surrogate model with improved accuracy
Numerical relativity simulations provide the most accurate waveforms for binary black hole coalescences, but are prohibitively expensive for direct use i...
Two more PhDs defended
Congratulations to Aniket Khairnar and Subhayu Bagchi on defending their PhDs! We had a double-header defense day, with Aniket in the morning and Subhayu in ...
Convergence of post-Newtonian for quasi-circular non-precessing comparable mass ratios BBHs
Post-Newtonian (PN) theory provides the analytic foundation for modeling the early inspiral of binary black holes. However, as an asymptotic series, succ...
