Observations of Colliding Reconnection Jets in the Solar Wind

The existence of multiple X-lines in a single current sheet is believed to generate flux ropes which appear as topological O-line regions (magnetic islands) in a 2D cross-section. The O-line region is also considered a place where the reconnection jets from two X-lines collide. We present the first multi-spacecraft observations at asymmetric current sheets in the solar wind which are in agreement with kinetic reconnection simulations of colliding jets. Current sheets in the solar wind thus support the formation of multiple X-lines and flux ropes.
