Gravitational multipoles from scattering amplitudes in higher dimensions
Francesco Campanella, Fabio Riccioni
We investigate the gravitational multipole structure derived from scattering amplitudes in both four- and higher-dimensional spacetimes, with particular focus on the five-dimension…
Couch-Torrence conformal inversion, supersymmetry and conserved charges for D3-branes
Mohammad Akhond, Massimo Bianchi, Antonio Cristofaro +1
An asymptotically flat spacetime in can be mapped via Couch-Torrence conformal inversion to the geometry around an extremal non-expanding and non-rotating horizon. At the lin…
The gyromagnetic factor of charged rotating black holes in various dimensions from scattering amplitudes
Claudio Gambino, Fabio Riccioni, Victor Sanz Sanchis
Classical black hole spacetimes can be recovered from the classical limit of quantum scattering amplitudes in a low-energy effective field theory of gravity. In this work we comput…
Probing the multipolar structure of Myers-Perry black holes with scattering amplitudes
Massimo Bianchi, Claudio Gambino, Fabio Riccioni +1
We discuss the scattering of massive scalar probes off Myers-Perry black holes in the Kerr-Schild gauge. Extending the analysis performed recently for Kerr(-Newman) black holes, we…
Rotating metrics and new multipole moments from scattering amplitudes in arbitrary dimensions
Claudio Gambino, Paolo Pani, Fabio Riccioni
We compute the vacuum metric generated by a generic rotating object in arbitrary dimensions up to third post-Minkowskian order by computing the classical contribution of scattering…
