Magnitude of Short-Wavelength Electric Field Fluctuations in Simulations of Collisionless Plasma Shocks
Vadim Roytershteyn, Lynn B. Wilson, Li-Jen Chen +2
Large-amplitude electrostatic fluctuations are routinely observed by spacecraft upon traversal of collisionless shocks in the heliosphere. Kinetic simulations of shocks have strugg…

Direct Measurements of Synchrotron-Emitting Electrons at Near-Sun Shocks
I. C. Jebaraj, O. V. Agapitov, M. Gedalin +22
In this study, we present the first-ever direct measurements of synchrotron-emitting heliospheric traveling shocks, intercepted by the Parker Solar Probe (PSP) during its close enc…

Acceleration of electrons and ions by an "almost" astrophysical shock in the heliosphere
Immanuel Christopher Jebaraj, Oleksiy Agapitov, Vladimir Krasnoselskikh +18
Collisionless shock waves, ubiquitous in the universe, are crucial for particle acceleration in various astrophysical systems. Currently, the heliosphere is the only natural enviro…
