Zigong Xu

Zigong Xu is a Postdoctoral Scholar Research Associate in Physics at the California Institute of Technology (Caltech), affiliated with the Division of Physics, Mathematics, and Astronomy. His research focuses on solar energetic particles (SEPs), heliospheric physics, and cosmic ray dynamics. His work leverages data from missions like Solar Orbiter, Parker Solar Probe, and Chang’E-4 to study particle acceleration mechanisms, interplanetary shock dynamics, and the propagation of energetic particles in the solar environment.

His research interests span solar flares, coronal mass ejection interactions, and the interplay between solar eruptions and the Earth-Moon radiation environment. He has contributed to understanding phenomena such as inverse velocity dispersion in SEPs, cosmic ray cavities in near-Earth space, and the composition variations of 3He-rich SEP events. Collaborations with multi-spacecraft missions highlight his expertise in analyzing particle data across diverse heliospheric distances.

Zigong has explored topics including galactic cosmic ray shielding on the lunar surface, thermodynamic properties of solar protons, and the role of coronal shocks in particle acceleration. His studies often involve advanced statistical methods and comparative analyses of observations from instruments like EPT and HET aboard Solar Orbiter, and ISOIS on Parker Solar Probe.

No formal awards or grants are explicitly mentioned, though his extensive publication record reflects active engagement in the field. He collaborates with international teams on missions such as Chang’E-4’s Lunar Lander Neutron and Dosimetry (LND) experiment, advancing lunar surface radiation studies.
