A transient enhancement of Mercury’s exosphere at extremely high altitudes inferred from pickup ions [PDF]
Nature Communications, 2020 Mercury has a global dayside exosphere that is very tenuous and does not extend far from the planet. Here, the authors show enhancement of neutral densities at high altitudes inferred from pickup ions that is most likely caused by the impact of a ...

Detection of Negative Pickup Ions at Saturn's Moon Dione [PDF]
Geophysical Research Letters, 2020 AbstractWe investigate a possible negative ion feature observed by the Cassini Plasma Spectrometer (CAPS) during a flyby of Saturn's moon Dione that occurred on 7 April 2010. By examining possible particle trajectories, we find that the observed particles are consistent with negative pickup ions originating near the moon's surface.

Pickup Ion–Mediated Magnetic Reconnection in the Outer Heliosphere
The Astrophysical Journal Letters, 2023 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 shock, and the heliopause.

Thermodynamics of Pickup Ions in the Heliosphere
The Astrophysical JournalThe paper shows the thermodynamic nature of the evolution of the pickup ion (PUI) distributions through their incorporation and subsequent expansion as the solar wind moves outward through the heliosphere.

Autonomous Cargo Transport with Biohybrid Microswimmers Enabled by Light-Mediated Bacteria-Cargo Communication. [PDF]
Adv MaterABSTRACT Biohybrid microswimmers, which integrate the unique mobility and taxis of living cells with the versatility of synthetic cargo, offer exciting opportunities for targeted delivery. However, current biohybrids lack autonomous decision‐making capabilities due to the absence of communication between living and synthetic components. Here, we report

Multipoint Density Measurements of Geocoronal Pickup Ions
Geophysical Research Letters, 2021 AbstractObservations of the plasma environment outside of the Earth's magnetosphere by the Magnetospheric Multiscale Mission Hot Plasma Composition Analyzers (MMS‐HPCAs) allow density measurements of geocoronal hydrogen pickup ions (PUIs). A study of this environment from December 4, 2019 to December 6, 2019, part of a single orbital period of the MMS ...

Scattering of Continuously Injected Pickup Ions of Oblique Pickup Angles in the Outer Heliosheath
The Astrophysical JournalPitch angle scattering of pickup ions (PUIs) in the outer heliosheath is studied using two-dimensional hybrid simulations, with the PUIs continuously injected at specified injection rates and pickup angles.

Energization of planetary pickup ions in the solar system [PDF]
Journal of Geophysical Research E: Planets, 2014 We study the solar wind‐induced ion escape from planetary atmospheres at different radial heliospheric distances in the solar system. We derive histograms of the gyroaveraged E×B velocities, energies, and Larmor radii of planetary ions in the solar wind at Mercury, Venus, Earth, and Mars.
