Extreme mass-ratio inspirals as probes of fundamental dipoles
Jacopo Lestingi, Enrico Cannizzaro, Paolo Pani
Even if globally neutral, in various scenarios compact objects can have a nonvanishing dipole moment. Examples include neutron stars with magnetic dipoles, black-hole microstates i…
Relativistic perturbation theory for black-hole boson clouds
Enrico Cannizzaro, Laura Sberna, Stephen R. Green +1
We develop a relativistic perturbation theory for scalar clouds around rotating black holes. We first introduce a relativistic product and corresponding orthogonality relation betw…
Novel tests of gravity using nano-Hertz stochastic gravitational-wave background signals
Enrico Cannizzaro, Gabriele Franciolini, Paolo Pani
Gravity theories that modify General Relativity in the slow-motion regime can introduce nonperturbative corrections to the stochastic gravitational-wave background~(SGWB) from supe…
Superradiance: Axionic Couplings and Plasma Effects
Thomas F. M. Spieksma, Enrico Cannizzaro, Taishi Ikeda +2
Spinning black holes can transfer a significant fraction of their energy to ultralight bosonic fields via superradiance, condensing them in a co-rotating structure or "cloud". This…
Nonlinear photon-plasma interaction and the black hole superradiant instability
Enrico Cannizzaro, Fabrizio Corelli, Paolo Pani
Electromagnetic field confinement due to plasma near accreting black holes can trigger superradiant instabilities at the linear level, limiting the spin of black holes and providin…
