First Sagittarius A* event horizon telescope results. VI. Testing the black hole metric
Astrophysical black holes are expected to be described by the Kerr metric. This is the only
stationary, vacuum, axisymmetric metric, without electromagnetic charge, that satisfies …

Nonlinear electrodynamics effects on the black hole shadow, deflection angle, quasinormal modes and greybody factors
In this paper, we discuss the effects of nonlinear electrodynamics (NED) on non-rotating
black holes, parametrized by the field coupling parameter β and magnetic charge parameter …

Superradiant evolution of the shadow and photon ring of Sgr
Ultralight bosons can affect the dynamics of spinning black holes (BHs) via superradiant
instability, which can lead to a time evolution of the supermassive BH shadow. We study …

Testing the rotational nature of the supermassive object M87* from the circularity and size of its first image
The Event Horizon Telescope (EHT) collaboration has recently released the first image of a
black hole (BH), opening a new window onto tests of general relativity in the strong field …

Superradiance evolution of black hole shadows revisited
Black hole (BH) shadows can be used to probe new physics in the form of ultralight particles
via the phenomenon of superradiant instability. By directly affecting the BH mass and spin …
