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…
From Quantum Amplitudes to Spacetime Geometry: a Multipolar Framework for Black Hole Signatures
Claudio Gambino
This thesis develops a unified framework that reconstructs the full classical content of General Relativity from the classical limit of quantum scattering amplitudes. By interpreti…
A Multipole-Based Framework for Kerr Black Hole Mimickers: From General Construction to a Specific Case of Study
Claudio Gambino
We present a novel systematic framework for engineering energy-momentum tensors in linearized gravity that generate gravitational fields with a prescribed multipolar structure, aim…
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…
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…
