             abstract = "By analysing a database of 26 yr 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 radio emissions. This allows us to 
                         demonstrate that the average emitted radio power is proportional 
                         to the Poynting flux from the rotating Jupiter's magnetosphere 
                         intercepted by the obstacle. We then generalize this result to the 
                         radio-magnetic scaling law that appears to apply to all plasma 
                         interactions between a magnetized flow and an obstacle, magnetized 
                         or not. Extrapolating this scaling law to the parameter range 
                         corresponding to hot Jupiters, we predict large radio powers 
                         emitted by these objects, that should result in detectable radio 
                         flux with new-generation radiotelescopes. Comparing the 
                         distributions of the durations of Ganymede-Jupiter and Io-Jupiter 
                         emission events also suggests that while the latter results from 
                         quasi-permanent Alfven wave excitation by Io, the former likely 
                         results from sporadic reconnection between magnetic fields 
                         Ganymede and Jupiter, controlled by Jupiter's magnetic field 
                         geometry and modulated by its rotation.",
