Geometric Capture and Optical Critical Curves of Purely Electric, Magnetic and Dyonic Black Holes in Einstein-Euler-Heisenberg Theory

Yong-Zhuang Li, An-Hao Xu, Haoyuan Luo +1

We examine background null capture in the electric, magnetic, and dyonic solutions of Einstein gravity coupled to a quartic Euler-Heisenberg-type electromagnetic Lagrangian. The ca…
