By analysing a database of 26 years of observations of Jupiter with the Nancay Decameter Array, we unambiguously identify the radio emissions caused by the Ganymede-Jupiter interaction. We study the energetics of these emissions via the distributions of their intensities, duration, and power, and compare them to the energetics of the Io-Jupiter rad...
Ancient hoops, usually made of wood or metal, do not survive archaeologically, but literary and iconographic representations provide information regarding the materials used, ergonomics, as well as their symbolic and cultural values. Hoops were intimately associated with youth, especially male, and this paper aims at expanding the understanding of ...
Este documento contiene el informe científico resultante después de más de cuatro años de investigación teórica y experimental sobre un tipo particular de sistemas físico-químicos llamados clatratos hidratos de gas. Estos sistemas son compuestos de inclusión constituidos por un armazón tridimensional de agua que aloja en sus cavidades moléculas de g...

In this work we describe a genetic algorithm which is used in order to study orbits of minor bodies in the frames of close encounters. We find that the algorithm in combination with standard orbital numerical integrators can be used as a good proxy for finding typical orbits of minor bodies in close encounters with planets and even their moons, sav...
We present high‐sensitivity Hubble Space Telescope (HST) Cosmic Origins Spectrograph and HST Space Telescope Imaging Spectrograph measurements of atmospheric OI 130.4‐nm and OI] 135.6‐nm emissions at Ganymede, which exhibit significant spatial and temporal variability. These observations represent the first observations of Ganymede using HST Cosmic...
The tenuous atmospheres of Jupiter's Galilean moons are key to understanding their interaction with the magnetosphere. The co-rotating magnetospheric plasma is locally perturbed at the moons and auroral emissions are generated in the moons' tenuous atmospheres. The perturbation generates Alfvén waves, which travel along Jupiter's field lines trigge...

A long chain of processes connects the satellite auroral footprints to the moon-magnetosphere interaction from which they originate. These processes include Alfvén waves’ generation, filamentation, reflection, and bi-directional electron acceleration. The Io footprint is the most studied auroral footprint, because it is both the brightest one and t...
As part of the ESA mission to Jupiter and Ganymede carried out by the Jupiter Icy Moons Explorer (JUICE) spacecraft, the Ganymede Laser Altimeter (GALA) will determine the topography and detect Ganymede’s tidal degree-2 signal in order to investigate the existence of a subsurface ocean and constrain its thickness. To deliver successful measurements...
