Black Hole Response Theory and its Exact Shockwave Limit
Lara Bohnenblust, Carl Jordan Eriksen, Jitze Hoogeveen +2
We present a black hole response formalism formulated within the worldline approach to the classical gravitational two-body problem. The central objects are response functions: a h…
Gravitational Bremsstrahlung in Black-Hole Scattering at : Quadratic-in-Spin Effects
Lara Bohnenblust, Harald Ita, Manfred Kraus +1
We are employing a supersymmetric variant of the worldline quantum field theory (WQFT) formalism to compute the far-field momentum-space gravitational waveform emitted during the s…
To bounce or not to bounce in generalized Proca theory and beyond
Lara Bohnenblust, Serena Giardino, Lavinia Heisenberg +1
It is notoriously difficult to construct a stable non-singular bouncing cosmology that avoids all possible instabilities throughout the entire evolution of the universe. In this wo…
Binary Kerr black-hole scattering at 2PM from quantum higher-spin Compton
Lara Bohnenblust, Lucile Cangemi, Henrik Johansson +1
Quantum higher-spin theory applied to Compton amplitudes has proven to be surprisingly useful for elucidating Kerr black hole dynamics. Here we apply the framework to compute scatt…
Gravitational Bremsstrahlung in Black-Hole Scattering at : Linear-in-Spin Effects
Lara Bohnenblust, Harald Ita, Manfred Kraus +1
We compute the far-field time-domain waveform of the gravitational waves produced in the scattering of two spinning massive objects. The results include linear-in-spin () coupli…
