We study the effect of sampling windows on derived shock and associated energetic storm particle (ESP) properties in 296 fast-forward interplanetary shocks using ACE measurements a…
Phase Coherence of Solar Wind Turbulence from the Sun to Earth
Masaru Nakanotani, Lingling Zhao, Gary P. Zank
The transport of energetic particles in response to solar wind turbulence is important for space weather. To understand charged particle transport, it is usually assumed that the p…
Pickup Ion-Mediated Magnetic Reconnection in the Outer Heliosphere
M. Nakanotani, G. P. Zank, L. -L. Zhao
Pickup ions (PUIs) play a crucial role in the heliosphere, contributing to the mediation of large-scale structures such as the distant solar wind, the heliospheric termination shoc…
On the seed population of solar energetic particles in the inner heliosphere
Nicolas Wijsen, Gang Li, Zheyi Ding +5
Particles measured in large gradual solar energetic particle (SEP) events are believed to be predominantly accelerated at shocks driven by coronal mass ejections (CMEs). Ion charge…
Improving the Arrival Time Estimates of Coronal Mass Ejections by Using Magnetohydrodynamic Ensemble Modeling, Heliospheric Imager data, and Machine Learning
Talwinder Singh, Bernard Benson, Syed A. Z. Raza +4
The arrival time prediction of Coronal mass ejections (CMEs) is an area of active research. Many methods with varying levels of complexity have been developed to predict CME arriva…
The Structure and Origin of Switchbacks: Parker Solar Probe Observations
Jia Huang, J. C. Kasper, L. A. Fisk +25
Switchbacks are rapid magnetic field reversals that last from seconds to hours. Current Parker Solar Probe (PSP) observations pose many open questions in regard to the nature of sw…

Under quasi-radial interplanetary magnetic fields (IMF), foreshock turbulence can have an impact on the magnetosheath and cusps depending on the location of the quasi-parallel shoc…
Space Plasma Physics: A Review
Bruce T. Tsurutani, Gary P. Zank, Veerle J. Sterken +13
Owing to the ever-present solar wind, our vast solar system is full of plasmas. The turbulent solar wind, together with sporadic solar eruptions, introduces various space plasma pr…
