Motion of particles around a magnetically charged Euler-Heisenberg black hole with scalar hair and the Event Horizon Telescope
Dionysios P. Theodosopoulos, Thanasis Karakasis, George Koutsoumbas +1
We study the motion of uncharged particles and photons in the background of a magnetically charged Euler-Heisenberg (EH) black hole (BH) with scalar hair. The spacetime can be asym…

Scalarization of the Reissner-Nordström black hole with higher derivative gauge field corrections
Stella Kiorpelidi, Thanasis Karakasis, George Koutsoumbas +1
We discuss spontaneous scalarization of the Reissner-Nordström black hole in the presence of higher derivative gauge field corrections that arise in the context of string, as well…
