Silhouettes of invisible black holes
In general relativity, isolated black holes are invisible due to the infinitely large redshift of
photons propagating from the event horizon to a remote observer. However, the dark …

Probing a non-linear electrodynamics black hole with thin accretion disk, shadow, and deflection angle with M87* and Sgr A* from EHT
Non-linear interaction between the electromagnetic fields (EMF) occurs when vacuum
polarization in quantum electrodynamics (QED) happens. The field of non-linear …

Magnetically charged black holes from non-linear electrodynamics and the Event Horizon Telescope
Non-linear electrodynamics (NLED) theories are well-motivated extensions of QED in the
strong field regime, and have long been studied in the search for regular black hole (BH) …
