Geodesic structure and quasinormal modes of a tidally perturbed spacetime
Vitor Cardoso, Arianna Foschi
Tidal perturbations play an important role in the study of the dynamics in the classical two-body system. Understanding tidal effects in strong-field regions may allow one to use g…

The light ring and the appearance of matter accreted by black holes
Vitor Cardoso, Francisco Duque, Arianna Foschi
The geometry of black hole spacetimes can be probed with exquisite precision in the gravitational-wave window, and possibly also in the optical regime. We study the accretion of br…

Collective scalarization or tachyonization: when averaging fails
Vitor Cardoso, Arianna Foschi, Miguel Zilhao
Certain scalar-tensor theories of gravity provide negative-energy, tachyonic modes to a fundamental scalar inside matter, giving rise to non-perturbative phenomena around compact s…
