A bstract For a static and spherically symmetric black hole, a photon sphere is composed of
circular null geodesics of fixed radius, and plays an important role in observing the black …

A bstract In this paper, we construct scalarized rotating black holes within the framework of
Einstein-Maxwell-scalar models. These models incorporate non-minimal couplings that can …

In this paper, we study spontaneous scalarization of asymptotically anti-de Sitter charged
black holes in an Einstein–Maxwell-scalar model with a non-minimal coupling between the …

The fate of strong cosmic censorship is ultimately linked to the extendibility of perturbation
across the Cauchy Horizon and known to be violated in the near extremal region of a …

In this paper, we investigate the observational appearances of magnetically charged black
holes in Born–Infeld (BI) electrodynamics. We examine the effects of the magnetic charge …

Hod's proposal claims that the least damped quasinormal mode of a black hole must have
the imaginary part smaller than half of the surface gravity at the event horizon. The Strong …

A bstract We study time evolutions of charged scalar perturbations on the background of a
charged hairy black hole, in which the perturbations can be governed by a double-peak …

The extendibility of spacetime and the existence of weak solutions to the Einstein field
equations beyond Cauchy horizons is a crucial ingredient to examine the limits of general …

A bstract The strong cosmic censorship hypothesis has recently regained a lot of attention in
charged and rotating black holes immersed in de Sitter space. Although the picture seems to …

In this work, we study the shadow of Born–Infeld (BI) black holes with magnetic monopoles
and Schwarzschild black holes immersed in the BI uniform magnetic field. Illuminated by a …
