Joaquín Espinoza Troni is a PhD student at the Universidad de Chile (Chile). His research focuses on nonlinear phenomena and kinetic effects in space plasmas, particularly on the role of ponderomotive forces in planetary magnetospheres with nonthermal velocity distributions, which is the central topic of his doctoral thesis. He also investigates the formation of electron-scale magnetic holes in turbulent plasmas. The work presented at EGU25 explores a possible mechanism for the generation of electron-scale magnetic holes in the magnetosheath using a fully kinetic PIC simulation of freely decaying plasma turbulence. This study provides new insights into the role of electron-scale waves and nonlinear processes in their formation, and how turbulence dynamics can drive such mechanisms, with potential applications to observations in the Earth’s magnetosheath as well as other turbulent space environments, such as the solar wind and the terrestrial magnetotail.
