Distinguishing Black Holes from String-Inspired Euler-Heisenberg Theory Through Shadow Images

2025 · Preprints.org

Recently, an interesting doppelgänge black hole solution is obtained in the string-inspired Euler-Heisenberg theory, where the black holes have the same radii but share different charges. We found, however, they possess different ISCOs and photon …
