New insights into black hole scattering and gravitational waves unveiled

A new study achieves unprecedented accuracy in modelling extreme cosmic events like black hole and neutron star collisions by calculating the fifth post-Minkowskian (5PM) order, crucial for interpreting gravitational wave data from current and future observatories. The research reveals the surprising appearance of Calabi-Yau three-fold periods -- complex geometric structures from string theory and algebraic geometry -- within calculations of radiated energy and recoil, suggesting a deep connection between abstract mathematics and astrophysical phenomena. Utilizing over 300,000 core hours of high-performance computing, an international team demonstrated the power of advanced computational methods in solving complex equations governing black hole interactions, paving the way for more accurate gravitational wave templates and insights into galaxy formation.
