An Effective -Matrix Approach to Low-Frequency Waveforms from Black Hole Mergers
Katsuki Aoki, Feng-Yin Cheng, Andrea Cristofoli +2
We develop an on-shell description of low-frequency gravitational waveforms from black-hole mergers beyond leading order. Treating the strongly coupled merger as effective hard …
Black Hole Thermodynamics Meets On-Shell Amplitudes: Local Detailed Balance and Thermal Spectrum from Spin Universality and Unitarity
Dogan Akpinar, Katsuki Aoki, Andrea Cristofoli +2
We develop an on-shell framework for thermal dissipation and radiation by macroscopic objects, whose large degeneracy of internal states is encoded in their entropy. In this framew…
Resumming Scattering Amplitudes for Waveforms
Katsuki Aoki, Andrea Cristofoli
We develop a formalism to compute non-perturbative 5-point scattering amplitudes and apply it to gravitational waveforms in the two-body problem for arbitrary trajectories. Drawing…
