Electrostatic Plasma wave excitations at the interplanetary shocks
Manpreet Singh, Federico Fraschetti, Joe Giacalone
Over the last few decades, different types of plasma waves (e.g., the ion acoustic waves (IAWs), electrostatic solitary waves (ESWs), upper/lower hybrid waves, the Langmuir waves e…
Numerical Modeling of Energetic Electron Acceleration, Transport, and Emission in Solar Flares: Connecting Loop-top and Footpoint Hard X-Ray Sources
Xiangliang Kong, Bin Chen, Fan Guo +8
The acceleration and transport of energetic electrons during solar flares is one of the outstanding topics in solar physics. Recent X-ray and radio imaging and spectroscopy observa…
Solar Energetic Particle Acceleration at a Spherical Shock with the Shock Normal Angle Evolving in Space and Time
Xiaohang Chen, Joe Giacalone, Fan Guo
We present a 2D kinematic model to study the acceleration of solar energetic particles (SEPs) at a shock driven by a coronal mass ejection. The shock is assumed to be spherical abo…
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…
In-situ Measurement of the Energy Fraction in Supra-thermal and Energetic Particles at ACE, Wind, and PSP Interplanetary Shocks
Liam David, Federico Fraschetti, Joe Giacalone +3
The acceleration of charged particles by interplanetary shocks (IPs) can drain a non-negligible fraction of the plasma pressure. In this study, we have selected 17 IPs observed in-…
On the Energy Dependence of Galactic Cosmic Ray Anisotropies in the Very Local Interstellar Medium
Romina Nikoukar, Matthew E. Hill, Lawrence Brown +11
We report on the energy dependence of galactic cosmic rays (GCRs) in the very local interstellar medium (VLISM) as measured by the Low Energy Charged Particle (LECP) instrument on…
