Reconnection Preferentially Accelerates Light Ions at Ganymede's Magnetopause
Geophysical Research LettersJuno's flyby of Ganymede revealed ion composition in its vicinity with the Jovian Auroral Distributions Experiment–Ion (JADE‐I) instrument. Throughout this flyby, we derive species‐resolved ion density and velocity moments by decomposing the time‐of ...

Ganymede's UV Reflectance From Juno‐UVS Data
Geophysical Research Letters, 2022 During the Juno orbit 34 Ganymede encounter, the ultraviolet spectrograph mapped UV sunlight reflected by Ganymede from a closest approach altitude of 1,044 km, allowing us to study spatial variations in Ganymede's far ultraviolet reflectance at higher ...

Probing Ganymede’s Atmosphere with HST Lyα Images in Transit of Jupiter
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 ...

On the Representation of Ganymede in the Roman Mosaic of the Loves of Zeus from Astigi (Baetica)
Journal of Mosaic Research, 2020 The discovery in 2015 of the great mosaic so called of the Zeus’ Loves in Écija (Sevilla) comes to highlight again the quality of the mosaic heritage of the ancient Astigi, capital of the conventus astigitanus in Baetica.

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.

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 ...

Structural geology of Ganymede regional groove systems (60°N–60°S)
Journal of Maps, 2020 Brittle deformation on Ganymede surface is represented by grooves tectonic linear landforms. These are regional scale structures that show well-defined morphology from straight to curvilinear. High density of grooves occupies most of the light terrain of

The role of the Hall effect in the global structure and dynamics of planetary magnetospheres: Ganymede as a case study [PDF]
, 2015 We present high resolution Hall MHD simulations of Ganymede's magnetosphere demonstrating that Hall electric fields in ion-scale magnetic reconnection layers have significant global effects not captured in resistive MHD simulations. Consistent with local
