Numerical aspects of black hole superradiance
Giuseppe Lingetti
In this work we explore a numerical technique, based on the spherical harmonic decomposition and the discretization of the radial coordinate through Čebyšëv polynomial interpolatio…

Black hole superradiant instability for massive spin-2 fields
Oscar J. C. Dias, Giuseppe Lingetti, Paolo Pani +1
Due to coherent superradiant amplification, massive bosonic fields can trigger an instability in spinning black holes, tapping their energy and angular momentum and forming macrosc…

Superradiant instabilities by accretion disks in scalar-tensor theories
Giuseppe Lingetti, Enrico Cannizzaro, Paolo Pani
We study the superradiant instability in scalar-tensor theories of gravitation, where matter outside a black hole provides an effective mass to the scalar degree of freedom of the…
