"Waveforms" at the Horizon
Andrea Cipriani, Francesco Fucito, Carlo Heissenberg +2
We study perturbations induced by a light particle scattering off a Schwarzschild black hole. Exploiting recent results for the wave propagation in this geometry, we derive the fie…
From the confluent Heun equation to a new factorized and resummed gravitational waveform for circularized, nonspinning, compact binaries
Andrea Cipriani, Alessandro Nagar, Francesco Fucito +1
We introduce a new factorized and resummed waveform for circularized, nonspinning, compact binaries that leverages on the solution of the Teukolsky equation once mapped into a conf…
On Instantons at Large Charge
Andrea Cipriani, Raffaele Savelli
The large R-charge limit of two-point functions of chiral primary operators in rank-one superconformal field theories exhibits a universal behavior controlled by th…
Resumming Post-Minkowskian and Post-Newtonian gravitational waveform expansions
Andrea Cipriani, Giorgio Di Russo, Francesco Fucito +3
We derive formulae that resum, at a given order in the soft limit, the infinite series of Post-Minkowskian (small gravitational coupling) or Post-Newtonian (small velocities) corre…
Hamiltonian Neural Networks approach to fuzzball geodesics
Andrea Cipriani, Alessandro De Santis, Giorgio Di Russo +2
The recent increase in computational resources and data availability has led to a significant rise in the use of Machine Learning (ML) techniques for data analysis in physics. Howe…
