Turbulence-Driven Corrugation of Collisionless Fast-Magnetosonic Shocks

Immanuel Christopher Jebaraj, Mikhail Malkov, Nicolas Wijsen +4

Collisionless fast-magnetosonic shocks are often treated as smooth, planar boundaries, yet observations point to organized corrugation of the shock surface. A plausible driver is u…

Plasma instability in the front of ejected energetic electrons and Type III solar radiobursts

Vladimir Krasnoselskikh, Immanuel Christopher Jebaraj, Tom Robert Franck Cooper +7

Type III radio bursts are a signature of the flux of near-relativistic electrons ejected during solar flares. These bursts are frequently observed by spacecraft such as the Parker…

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…

Nonlinear resonant interactions of radiation belt electrons with intense whistler-mode waves

A. V. Artemyev, D. Mourenas, X. -J. Zhang +8

The dynamics of the Earth's outer radiation belt, filled by energetic electron fluxes, is largely controlled by electron resonant interactions with electromagnetic whistler-mode wa…

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…

On the origin of the type-III radiation observed near the Sun

Forrest Mozer, Oleksiy Agapitov, Stuart Bale +5

To investigate processes associated with generation of type-III radiation. Measure the amplitudes and phase velocities of Parker Solar Probe ob…
