The mass distribution in the Galactic Centre from interferometric astrometry of multiple stellar orbits
GRAVITY Collaboration, R. Abuter, N. Aimar +62
The stars orbiting the compact radio source Sgr A* in the Galactic Centre are precision probes of the gravitational field around the closest massive black hole. In addition to adap…
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…
