Introduction
The Introduction, after a definition of the plasma state, contains a brief history of the magnetic reconnection research field starting from the first insight of Giovanelli in 1939 to the in situ near-Earth me...

Magnetic Reconnection at the Earth’s Magnetosphere
This chapter provides information about the physical context in which the magnetic reconnection process is studied in this Thesis, namely the near-Earth space. Magnetopause reconnection directly mediates the i...

Numerical Models for Astrophysical Plasmas
This chapter is meant to briefly present the different numerical models that are commonly used to study astrophysical plasmas. Section 5.1 recalls the kinetic description of a plasma eventually deriving the Vl...

Chapter
The Electron Diffusion Region
The previous chapters are mainly focused on the MHD and two fluid description of magnetic reconnection. In these theoretical frameworks, the EDR is depicted as a “black box” where magnetic field lines change t...

In Situ Spacecraft Observations of a Structured Electron Diffusion Region During Magnetopause Reconnection
This chapter presents observations providing evidence of a structured EDR at the . In particular, I present and discuss the results presented in Cozzani et al. (2019) and I include analysis that could not be ful...
