Observational Signatures: Shadow cast by the effective metric of photons for black holes with rational non-linear electrodynamics

Understand

This study explores spherically symmetric non-linear electrodynamics black holes and their effects on light propagation.

• We derive the governing metric, revealing radial coordinate dynamics within the event horizon.
• We analyze photon trajectories, finding that increasing magnetic charge expands the horizon and emission range.
• Furthermore, with the help of the Event Horizon Telescope results, we constrain parameters and emission profiles.
