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…

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…
