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

A Common Origin for Ridge-and-Trough Terrain on Icy Satellites by Sluggish Lid Convection [PDF]
, 2015 Ridge-and-trough terrain is a common landform on outer Solar System icy satellites. Examples include Ganymede's grooved terrain, Europa's gray bands, Miranda's coronae, and several terrains on Enceladus.

The NIR transmission spectrum of Jupiter from the observation of a Ganymede’s eclipse
EPJ Web of Conferences, 2015 Here, we report the NIR transmission spectrum of Jupiter, with high signal-to-noise ratio, as if it were a transiting planet. Our technique was to observe Ganymede, when crossing Jupiter’s shadow.

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

Early Stages of Galilean Moon Formation in a Water-depleted Environment
The Astrophysical Journal Letters, 2023 A key feature of the Galilean satellite system is its monotonic decrease in bulk density with growing distance from Jupiter, indicating an ice mass fraction that is zero in the innermost moon Io and about half in the outer moons Ganymede and Callisto ...

The generation of Ganymede's diffuse aurora through pitch angle scattering [PDF]
Annales Geophysicae, 2017 Diffuse auroral intensities of neutral atomic oxygen OI λ1356 Å emission on Ganymede due to whistler mode waves are estimated. Pitch angle diffusion of magnetospheric electrons into the loss cone due to resonant wave–particle interaction of whistler ...

Jupiter as an exoplanet: UV to NIR transmission spectrum reveals hazes, a Na layer and possibly stratospheric H2O-ice clouds [PDF]
, 2015 Currently, the analysis of transmission spectra is the most successful technique to probe the chemical composition of exoplanet atmospheres. But the accuracy of these measurements is constrained by observational limitations and the diversity of possible ...
