AB: Using a three-dimensional Vlasov code we investigate the unstable generation of waves and reconnection in thin, collisionless current sheets with guide fields and in magnetopause-like configurations. The amplitude of the saturated waves appears to critically control the moment of initiation of reconnection, it determines the mode of reconnection, whether it is essentially two-dimensional or three-dimensional as well as the reconnection rate. In the guide field case of non-antiparallel reconnection a transition from regular, well structured, to patchy reconnection and percolation is possible, but in the asymmetric magnetopause-like case we recover the formation of islands reminding flux transfer events.
