A bstract We introduce a—somewhat holographic—dictionary between gravitational
observables for scattering processes (measured at the boundary) and adiabatic invariants …

A bstract We continue to investigate correspondences between, on the one hand, scattering
amplitudes for massive higher-spin particles and gravitons in appropriate quantum-to …

We demonstrate equivalences, under simple mappings, between the dynamics of three
distinct systems—(i) an arbitrary-mass-ratio two-spinning-black-hole system,(ii) a spinning …

A bstract We construct two-dimensional quantum states associated to four-dimensional
linearized rotating self-dual black holes in (2, 2) signature Klein space. The states are …

A bstract We show that large gauge transformations modify the structure of momentum
conservation leading to non-vanishing three-point amplitudes in a simple toy model of a …

A bstract We derive the classical gravitational radiation from an aligned spin binary black
hole on closed orbits, using a dictionary built from the 5-point QFT scattering amplitude of …

Extreme-mass-ratio inspirals (EMRIs) will be key sources for LISA. However, accurately
extracting system parameters from a detected EMRI waveform will require self-force …

Gravitational self-force theory is the primary way of modeling extreme-mass-ratio inspirals
(EMRIs). One difficulty that appears in second-order self-force calculations is the strong …

The laws of geometric optics and their corrections are derived for scalar, electromagnetic,
and gravitational waves propagating in generic curved spacetimes. Local peeling-type …

We extend recent theoretical results on the propagation of linear gravitational waves (GWs),
including their associated memories, in spatially flat Friedmann–Lemaître–Robertson …
