Nonsingular black holes in nonlinear gravity coupled to Euler-Heisenberg electrodynamics.

We study static, spherically symmetric black holes supported by the Euler-Heisenberg theory of electrodynamics and coupled to two different modified theories of gravity. Such theories are the quadratic f (R) model and Eddington-inspired Born-Infeld gravity, both formulated in metric-affine spaces, w...

description We study static, spherically symmetric black holes supported by the Euler-Heisenberg theory of electrodynamics and coupled to two different modified theories of gravity.
