Light Deflection and Greybody Bound Around a BTZ-ModMax Black Hole in Plasma Medium

We study the deflection of light in a homogeneous plasma medium around a BTZ-ModMax black hole, focusing on the effects of the ModMax nonlinear electrodynamics parameter and the cosmological constant. Using the Gauss-Bonnet theorem applied to the corresponding optical geometry in...

Strong Gravitational Lensing by Lorentzian-Euclidean Black Hole

We investigate the strong gravitational lensing properties of the Lorentzian Euclidean black hole, a spacetime in which the horizon at [Formula: see text] is not a coordinate singularity but a genuine surface of signature change, with the associated curvature singularities remove...
