Every modern scientist faces the challenge of building a community to promote their project and turn it into a reality. But how do we move from a fragmented group of individuals to a proactive, recognizable, and collaborative network? In this presentation, I …

The moon Io, the most volcanically active body in the Solar System, functions as the “energy converter” of the Jovian environment: tidal heating by Jupiter and its Galilean satellites powers intense outgassing that sustains both the neutral and plasma tori and feeds …

Context . Ganymede is the only moon in the Solar System with an intrinsic magnetic field that actively interacts with the Jupiter magnetosphere. This precipitates energetic electrons that generate ultraviolet (UV) auroral emission. Aims . In sunlit auroral regions, the observed emission …

Jupiter’s magnetosphere is often presented as a template for fast-rotating magnetospheres. Distinct from Earth-like, solar wind-driven magnetospheres, it contains an extended magnetodisk encircling the planet. Although the magnetodisk has been studied since the 1970s, its stability and non-equilibrium dynamics remain poorly understood. …

Abstract The outward transport of plasma and magnetic fluxes in the gas giant magnetospheres is balanced with a return flow of flux tubes emptied through magnetic reconnection. Evidence of interchange motions between inward and outward moving flux tubes have long been reported …

Context . Ganymede’s UV aurorae, observed by HST and Juno/UVS, trace interactions between its atmosphere and Jupiter’s magneto-sphere. These emissions, dominated by O I lines at 130.4 and 135.6 nm, are driven by electron impact on species such as H 2 O, …

Abstract Whistler‐mode waves play a crucial role in shaping magnetospheric electron dynamics. Using Juno's observations, we investigate these waves in Jupiter's post‐midnight‐to‐dawn magnetosphere, spanning 20–80 Jupiter radii. Our survey reveals that whistler‐mode waves predominantly occur in the lobes, while the magnetodisk remains …

Abstract Previous observations in Jupiter's magnetosphere have revealed that the pitch‐angle distributions (PADs) of energetic ( keV) electrons transition from pancake to field‐aligned distributions from 10 to 20 Jupiter radii. Here, by analyzing Juno/JADE‐E data, we show that a similar transition also …

Supercell thunderstorms are among the most damaging and hazardous weather phenomena. Due to heterogeneous observation networks, no comprehensive and homogeneous observation-based supercell climatology exists for Europe. Utilizing a km-scale 11-year current climate simulation, we derive a climatology for supercell thunderstorms in Europe, …

Abstract Jupiter's moon Callisto orbits in a highly variable magnetospheric environment depending on its position relative to the Jovian current sheet. The Juno and Galileo missions have visited the Jovian magnetosphere and crossed Callisto's orbit several times in a variety of configurations, …
