“…Elucidating the kinetic dynamics of thin current sheet equilibria is essential for understanding many fundamental plasma energization phenomena, such as the onset of magnetic reconnection, plasma turbulence, and wave instabilities (Harris, ; Priest, ; Daughton, ; Sundkvist et al, ). Detection of electron‐scale current sheets in Earth's magnetic environment has become possible with the high‐resolution instrumentation onboard the Magnetospheric Multiscale (MMS) spacecraft, which can resolve electron skin depth ( d e ) scale, filamentary currents narrower than the spacecraft separation (Phan et al, ; Phan et al, ; Yordanova et al, ; Wilder et al, ). Current sheets with thicknesses on the order of a few d e are often observed in association with the electron diffusion region (EDR) and separatrix regions of magnetic reconnection (Burch et al, ; Chen et al, ; Chen et al, ; Genestreti et al, ; Norgren et al, ; Torbert et al, ; Torbert et al, ; Wang et al, ; Webster et al, ).…”
