Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-9 (2023)

Abstract Our knowledge about the fine structure of lightning processes at Jupiter was substantially limited by the time resolution of previous measurements. Recent observations of the Juno mission revealed electromagnetic signals of Jovian rapid whis

Intense electromagnetic impulses induced by Jupiter’s lightning can produce both low-frequency dispersed whistler emissions and non-dispersed radio pulses. Here, the authors show Jupiter dispersed pulses associated with Jovian lightning that are ev

Jupiter’s magnetic field and the generation and control of decameter radiation observed by the Juno spacecraft during the prime mission

Autor: Yasmina M Martos, John Connerney, Masafumi Imai, William Farrell, William Kurth

Decametric radio emissions (DAM) originating in Jupiter’s polar magnetosphere ought to originate on magnetic field lines at the local electron gyrofrequency. The Io-related DAM have received the most attention since the 1980’s. The maximum freque

Juno Plasma Wave Observations at Ganymede

Autor: William S Kurth, Ali H. Sulaiman, George Blair Hospodarsky, John Douglas Menietti, Barry H. Mauk, George Clark, Frederic Allegrini, Philip Valek, John E. P. Connerney, Jack Hunter Waite, Scott J Bolton, Masafumi Imai, Ondrej Santolik, Wen Li, Stefan Duling, Joachim Saur, Corentin Kenelm Louis

The Juno Waves instrument measured plasma waves associated with Ganymede's magnetosphere during its flyby on 7 June, day 158, 2021. Three distinct regions were identified including a magnetotail/wake, and nightside and dayside regions in the main mag

A Coherent Method for Simulating Active and Passive Radar Sounding of the Jovian Icy Moons

Autor: Lorenzo Bruzzone, Masafumi Imai, Christopher Gerekos

Publikováno v: IEEE Transactions on Geoscience and Remote Sensing. 58:2250-2265

The possibility to apply passive radar sounding techniques to the Jovian icy moons, making use of Jupiter’s strong decametric emissions (DAMs), has recently garnered large research interest. In this article, we propose a radar sounding simulation a
