Περίληψη: In this work, we explore the possibility of Schwinger pair creation triggered by magneto-centrifugal effects in the magnetosphere of Sgr A*. We show that these effects become extremely efficient in the presence of a vortex-driven magnetic field, whose strength exceeds previous estimates by several orders of magnitude. The dynamics of magneto-centrifugally accelerated charged particles leads to charge separation, thereby parametrically exciting Langmuir waves. The associated electric field grows exponentially and, upon reaching the Schwinger critical threshold, initiates efficient electron–positron pair production, which is ultimately saturated by annihilation processes.
