In a study published in The Astrophysical Journal, researchers from the University of California, Los Angeles, and the Instituto Superior Técnico, Universidade de Lisboa, have investigated magnetic reconnection in lunar-relevant mini-magnetospheres. The team, including Filipe D. Cruz, Fábio Cruz, and Luis O. Silva from the Instituto Superior Técnico, used advanced laboratory experiments and particle-in-cell simulations using the code OSIRIS to uncover critical insights into the microphysics of collisionless space plasmas. Their findings reveal the formation of Hall fields and electron-only reconnection driven by kinetic effects, contributing to our understanding of space plasma dynamics near the lunar surface.
