An Adaptive Approach for Modeling Collisionless Plasma Shocks and Ion Heating in the Shock Frame
Yuri A. Omelchenko, Igor V. Sokolov, Lulu Zhao +2
We present a novel computational method for hybrid (kinetic ions, quasi-neutral fluid electrons) simulations of non-relativistic magnetized collisionless plasma shocks, observed ne…
Advancing Heliophysics and Space Weather Modeling through Open Science
C. Corti, M. M. Kuznetsova, M. A. Reiss +85
We present a community-wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potenti…
Simulation Models for Exploring Magnetic Reconnection
Michael Shay, Subash Adhikari, Naoki Beesho +22
Simulations have played a critical role in the advancement of our knowledge of magnetic reconnection. However, due to the inherently multiscale nature of reconnection, it is imposs…

Magnetopause reconnection and indents induced by foreshock turbulence
Li-Jen Chen, Jonathan Ng, Yuri Omelchenko +1
Based on global hybrid simulation results, we predict that foreshock turbulence can reach the magnetopause and lead to reconnection as well as Earth-sized indents. Both the interpl…
Electron acceleration by magnetosheath jet-driven bow waves
Terry Z. Liu, Heli Hietala, Vassilis Angelopoulos +2
Magnetosheath jets are localized fast flows with enhanced dynamic pressure. When they supermagnetosonically compress the ambient magnetosheath plasma, a bow wave or shock can form…
Statistical study of magnetosheath jet-driven bow waves
Terry Z. Liu, Heli Hietala, Vassilis Angelopoulos +3
When a magnetosheath jet (localized dynamic pressure enhancements) compresses ambient magnetosheath at a (relative) speed faster than the local magnetosonic speed, a bow wave or sh…
