Short summary
Short summary
Magnetic reconnection is a key process in space and laboratory plasmas which transfers energies through the magnetic field topology change. The topology change in this process takes place in a small scale region called the electron diffusion region (EDR). In this paper, using high-resolution fully kinetic simulations, we successfully obtained the firm scaling laws of spatial dimensions of the EDR. The obtained scalings allow us to precisely predict observable dimensions of the EDR in real space.

Short summary
A novel data analysis technique for recovering three-dimensional (3-D) magnetic field structures from in situ measurements by two satellites is applied for the first time to a magnetic flux rope observed by the THEMIS spacecraft near the Earth's subsolar magnetopause. We found that the flux rope resulting from multiple X-line reconnection was significantly 3-D and consisted of the field lines with different topologies, suggesting a complex interaction of the solar wind and the magnetosphere.
