Black Hole Mergers as the Fastest Photon Ring Scramblers
D. Giataganas, G. F. Giudice, A. Ianniccari +5
Black holes are the most efficient scramblers in nature. By mapping the instantaneous mass and angular momentum of two spinless black holes in a quasi-circular binary onto those of…

Nonlinear Gravity and Multipole Turbulence
A. Ianniccari, A. Kehagias, L. Lo Bianco +1
We derive a kinetic Boltzmann equation characterizing the long-term statistical behavior of the turbulent dynamics of nonlinear interacting gravitational wave multipoles in Minkows…

The Irrelevance of Primordial Black Hole Clustering in the LVK mass range
F. Crescimbeni, V. Desjacques, G. Franciolini +6
We show that in realistic models where primordial black holes are formed due to the collapse of sizeable inflationary perturbations, their initial spatial clustering beyond Poisson…
