Abstract

Regularized Maxwell electrodynamics is a recently discovered theory of nonlinear electrodynamics, with a minimally regularized field strength of a point charge, that is very close to the Maxwell theory in many aspects. In this paper we investigate some of the optical properties of its black holes. Namely, we study geodesics, gravitational redshift, black hole shadow, as well as investigate the relationship between the behavior of (null geodesic) Lyapunov exponents and the existence of thermodynamic critical points in both canonical and grand-canonical ensembles.
