Sgr A* as a Galactic PeVatron: Multimessenger Signatures of the Magnetic Penrose Process

Marina Cermeño, Pedro De la Torre Luque, Cristina Fernández-Suárez +5

The magnetic Penrose process (MPP) is one of the most efficient mechanisms for extracting rotational energy from a magnetized Kerr black hole (BH), enabling charged particles to re…
