Description
Relativistic jets are launched in the immediate vicinity of black holes and emit radiation across the entire electromagnetic spectrum. According to our current understanding, these powerful outflows are driven by extracting rotational energy from spinning black holes via the Blandford–Znajek mechanism. Numerical simulations have further demonstrated that the accumulation of magnetic flux onto the black hole is a critical ingredient for jet formation and collimation. In this talk, we focus on the microscopic processes that govern electromagnetic emission within these jets. Specifically, we explore how Particle-in-Cell (PIC) simulations reveal the role of magnetic reconnection in accelerating particles to relativistic energies.
