Advancing Theory and Modeling Efforts in Heliophysics

Fan Guo, Spiro Antiochos, Paul Cassak +15

Heliophysics theory and modeling build understanding from fundamental principles to motivate, interpret, and predict observations. Together with observational analysis, they consti…

Double-power-law feature of energetic particles accelerated at coronal shocks

Feiyu Yu, Xiangliang Kong, Fan Guo +4

Recent observations have shown that in many large solar energetic particle (SEP) events the event-integrated differential spectra resemble double power laws. We perform numerical m…

Astrophysical explosions revisited: collisionless coupling of debris to magnetized plasma

Ari Le, Dan Winske, Adam Stanier +4

The coupling between a rapidly expanding cloud of ionized debris and an ambient magnetized plasma is revisited with a hybrid (kinetic ion/fluid electron) simulation code that allow…

Efficient Nonthermal Ion and Electron Acceleration Enabled by the Flux-Rope Kink Instability in 3D Nonrelativistic Magnetic Reconnection

Qile Zhang, Fan Guo, William Daughton +2

The relaxation of field-line tension during magnetic reconnection gives rise to a universal Fermi acceleration process involving the curvature drift of particles. However, the effi…

The Acceleration of Charged Particles and Formation of Power-law Energy Spectra in Nonrelativistic Magnetic Reconnection

Xiaocan Li, Fan Guo, Yi-Hsin Liu

Magnetic reconnection is a primary driver of particle acceleration processes in space and astrophysical plasmas. Understanding how particles are accelerated and the resulting parti…

First-Principle Prediction of X-ray Polarization from Magnetic Reconnection in High-Frequency BL Lacs

Haocheng Zhang, Xiaocan Li, Dimitrios Giannios +1

Relativistic magnetic reconnection is a potential particle acceleration mechanism for high-frequency BL Lacs (HBLs). The {\it Imaging X-ray Polarimetry Explorer} ({\it IXPE}) sched…
