Scalar shortcut to beyond-Kerr ringdown tests and their complementarity with black-hole shadow observations
Paolo Pani, Andrea P. Sanna
The quasinormal modes of black holes (BHs) in the large-angular-momentum limit can be computed within the eikonal approximation. This approximation is often extrapolated to low ang…

Weak Cosmic Censorship with spinning particles in Kerr-(A)dS spacetimes
Antonia M. Frassino, Jorge V. Rocha, Andrea P. Sanna
We investigate the weak cosmic censorship conjecture by analyzing the dynamics of spinning timelike particles dropped along the rotational axis of an extremal Kerr (anti)de Sitter…

Weak cosmic censorship and the rotating quantum BTZ black hole
Antonia M. Frassino, Jorge V. Rocha, Andrea P. Sanna
Tests of the weak cosmic censorship conjecture examine the possibility of the breakdown of predictivity of the gravitational theory considered, by checking if curvature singulariti…
