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…

Source multipoles and energy-momentum tensors for spinning black holes and other compact objects in arbitrary dimensions

Massimo Bianchi, Claudio Gambino, Paolo Pani +1

Working in momentum space and at linear order in the gravitational coupling, we derive the most general class of energy-momentum tensors associated with a given multipolar structur…
