Confining nonlinear electrodynamics black holes: from thermodynamic phases to high-frequency phenomena with accretion process
Erdem Sucu, Izzet Sakallı, Orhan Donmez +1
We investigate a static, spherically symmetric black hole solution arising from Einstein gravity coupled to a confining nonlinear electrodynamics model that reproduces Maxwell theo…
