Recent years have seen significant advancements in employing tools from Quantum Field Theory, specifically techniques from the modern Amplitudes program, to inform theoretical predictions for gravitational waveforms generated by binary systems. In this talk I will review this effort, emphasizing especially two aspects:
1. Modeling the spin of astrophysical objects will become increasingly important for signal identification as the sensitivity of gravitational-wave detectors will continue to improve. I will discuss how using Amplitudes methods we have obtained new results pertaining to the gravitational interaction of spinning objects and identified novel physical phenomena that may manifest in the gravitational waveform.
2. Extreme-mass-ratio binary systems will be a significant source of gravitational-wave signals for the Laser Interferometer Space Antenna (LISA). I will introduce a Quantum Field Theoretic framework for modeling such systems, which leverages exact solutions to Einstein’s equations to compute classes of contributions to all orders in the gravitational coupling G but as an expansion in the mass ratio.
I will conclude by discussing the next steps towards meeting the precision goals of the future gravitational-wave observatories.
