First observation of a solar-like magnetic reconnection flare in NGC 3783 AGN corona, identified via Neupert effect in X-ray timing and an ultra-fast outflow analogous to a solar CME.

PIC simulations show E·B ≠ 0 regions reduce magnetic helicity in sub-ion turbulence, and a new history-dependent helicity density produces time-independent intermediate-scale plateaus consistent with cancellation-dominated 2D decay.
Numerical experiment shows alternating-current-driven waves cause a magnetic null to collapse into y-directed then x-directed current sheets, with Hall effect producing lagged out-of-plane flows whose amplitudes increase with driving strength.
