Integrable models of inflation beyond slow-roll
M. Bianchi, G. Dibitetto, J. F. Morales +1
We propose a novel analytic approach to the study of multi-component FLRW cosmologies and their perturbations. The dynamics is triggered by a single scalar field with a scalar pote…

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…
