In recent years, unprecedented progress has been achieved regarding black holes'
observation through the electromagnetic channel. The images of the supermassive black …

We construct a charged rotating black hole in 4D Einstein–Gauss–Bonnet (EGB) gravity
starting from charged black hole in 4D EGB gravity using complex coordinate …

Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

Our understanding of strong gravity near supermassive compact objects has recently
improved thanks to the measurements made by the Event Horizon Telescope (EHT). We use …

Climate change is profoundly affecting nearly all aspects of life on earth, including human
societies, economies, and health. Various human activities are responsible for significant …

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 …

We discuss equivalent representations of gravity in the framework of metric-affine
geometries pointing out basic concepts from where these theories stem out. In particular, we …

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 …

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 …

Non-linear interaction between the electromagnetic fields (EMF) occurs when vacuum
polarization in quantum electrodynamics (QED) happens. The field of non-linear …
