A Simulation Pipeline for Nearly Circular Supermassive Black Hole Binaries

Learn about a groundbreaking simulation pipeline for studying nearly circular supermassive black hole binaries in this 32-minute conference talk from the Workshop on "Lensing and Wave Optics in Strong Gravity" at ESI. Explore how simulation-based modeling supports very long baseline interferometry observations and gravitational wave detections, while discovering innovative approaches to future multimessenger observations of supermassive binary black holes (SMBBHs). Dive into the technical details of general relativistic magnetohydrodynamic (GRMHD) simulations and general relativistic radiative transfer (GRRT) calculations, utilizing publicly available tools including the spectral solver Kadath, GRMHD code BHAC, and GRRT code BHOSS. Understand how the approximate helical symmetry of binary black hole spacetimes reduces computational costs while maintaining accurate general relativistic dynamics, and examine current applications in modeling SMBBH phenomenology.
