Along the last decades, several regular black hole (BH) solutions, i.e., singularity-free BHs, have been proposed and associated to nonlinear electrodynamics models minimally coupled to general relativity. Within this context, it is of interest to study how those nonlinear-electrodynamic-based regular BHs (RBHs) would interact with their astrophysical environment. We investigate the propagation of a massless test scalar field in the background of an electrically charged RBH solution, obtained… 
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 P in detail.
Absorption cross section of regular black holes in scalar-tensor conformal gravity
In terms of the complex angular momentum method, we compute the absorption cross section by analyzing a massless test scalar field around conformally related black holes. At first, we investigate
Dyonically Charged Black Holes Arising in Generalized Born--Infeld Theory of Electromagnetism
Black hole solutions to the Einstein equations coupled with the Born–Infeld electromagnetism associated with generalized nonlinear electrodynamics, carrying both electric and magnetic charges, often
Bardeen-Kiselev black hole with a cosmological constant
In this work we analyze a solution that mimics the Bardeen solution with a cosmological constant surrounded by quintessence. We show that this solution can be obtained by Einstein equations coupled
Electromagnetic Asymmetry, Relegation of Curvature Singularities of Charged Black Holes, and Cosmological Equations of State in View of the Born--Infeld Theory
It is shown that, in a generic sense, and unlike what for electric point charges, the Born– Infeld nonlinear electrodynamics excludes monopoles as finite-energy magnetic point charges, thus spelling

Accretion of fields by black holes is a subject of great interest in physics. It is known that accretion plays a fundamental role in active galactic nuclei and in the evolution of black holes.

It is shown that general relativity coupled to nonlinear electrodynamics (NED) with the Lagrangian $L(F)$, $F = F_mn F^mn$ having a correct weak field limit, leads to nontrivial static, spherically
