A bstract Using a heavy-mass effective field theory (HEFT), we study gravitational-wave
emission in the scattering of two spinless black holes or neutron stars of arbitrary masses at …

A bstract We compute the classical tree-level five-point amplitude for the two-to-two
scattering of spinning celestial objects with the emission of a graviton. Using this five-point …

We propose that the dynamics of Kerr black holes is strongly constrained by the principle of
gauge symmetry. We initiate the construction of effective field theories for Kerr black holes of …

We develop a novel amplitude bootstrap technique manifestly free of unphysical poles for
classically spinning particles interacting with gravitons utilizing only the double-copy and …

A bstract We introduce a novel bootstrap method for heavy-mass effective field theory
classical Compton scattering amplitudes involving two massless particles and two arbitrary …

Scattering angles for probes in Kerr metrics are derived for scattering in the equatorial plane
of the black hole. We use a method that naturally resums all orders in the spin of the Kerr …

A bstract We construct a new Yang-Mills Lagrangian based on a notion of minimal coupling
that incorporates classical spin effects. The construction relies on the introduction of a new …

A bstract We study gravitational absorption effects using effective on-shell scattering
amplitudes. We develop an in-in probability-based framework involving plane-and partial …

A bstract We study the EFT of a spinning compact object and show that with appropriate
gauge fixing, computations become amenable to worldline quantum field theory techniques …
