Probing Ganymede’s Atmosphere with HST Lyα Images in Transit of Jupiter [PDF]
The Planetary Science Journal, 2023 We report results from far-ultraviolet observations by the Hubble Space Telescope of Jupiter’s largest moon, Ganymede, transiting across the planet’s dayside hemisphere.

On Ganymede’s Magnetic Quadrupolar Strength
The Planetary Science Journal, 2023 Ganymede is the only moon in our solar system known to have a large-scale intrinsic magnetic field, likely generated in the moon’s metallic core. Initial analyses of Galileo spacecraft measurements concluded that Ganymede’s intrinsic magnetic field is ...

Updated Spherical Harmonic Magnetic Field Moments of Ganymede From the Juno Flyby
Geophysical Research Letters, 2022 In this study, we use data from the Juno and Galileo spacecraft to analyze the internal magnetic dynamo of Ganymede. As the only known moon with a strong internal magnetic field, Ganymede is a uniquely interesting object in the context of understanding ...

Three-dimensional Magnetohydrodynamic Simulations of Periodic Variations of Ganymede’s Footprint
The Astrophysical JournalAlfvénic power is generated through the interaction between the mini-magnetosphere of Ganymede and the corotating flow of the Jovian plasma, contributing to the formation of the Ganymede auroral footprint at Jupiter’s ionosphere.

Backscattering of Ions Impacting Ganymede’s Surface as a Source for Energetic Neutral Atoms
The Astrophysical Journal LettersJupiter’s largest moon Ganymede has its own intrinsic magnetic field, which forms a magnetosphere that is embedded within Jupiter’s corotating magnetospheric plasma.

Ganymede's Radiation Cavity and Radiation Belts
Geophysical Research Letters, 2022 While planetary radiation belts are all embedded within the low energy solar wind, Ganymede is in the unique situation of being surrounded by the energetic particles of Jupiter's magnetosphere.

New Polarimetric Data for the Galilean Satellites: Io and Ganymede Observations and Modeling
The Planetary Science JournalNew high-precision disk-integrated measurements of the polarization of Io and Ganymede in the UBVRI bands are presented. The observations were obtained using polarimeters mounted on the Crimean Astrophysical Observatory and the Peak Terskol Observatory ...

Evidence for Magnetic Reconnection at Ganymede's Upstream Magnetopause During the PJ34 Juno Flyby
Geophysical Research Letters, 2022 Juno made a close flyby of Ganymede and flew through its magnetosphere on 7 June 2021, including an outbound crossing of Ganymede's upstream magnetopause. We present plasma and magnetic field observations near the upstream magnetopause from Juno's Jovian

Energetic Charged Particle Fluxes Relevant to Ganymede's Polar Region
Geophysical Research Letters, 2022 The JEDI instrument made measurements of energetic charged particles near Ganymede during a close encounter with that moon. Here we find ion flux levels are similar close to Ganymede itself but outside its magnetosphere and on near wake and open field ...
