Proposal Summary:
We propose to systematically investigate the physics of Jovian radio emissions by using data analysis and computer modeling techniques. The unique orbiting platform of the primary and GEM missions of the Galileo spacecraft have produced a wealth of data that is invaluable for statistical and empirical studies of Jovian radio emission. The data contain information about the beaming angles, source location, and generation mechanism of the KOM, HOM, and DAM emissions, as well as the quasiperiodic emissions. For the proposed research, in addition to statistical studies, we will apply spin-modulation analysis and ray tracing techniques to identify potential radio source locations of the Jovian DAM (3-6 MHz), HOM (0.5-3 MHz) and KOM (20-500 kHz) radio components. Plasma wave data will be compared to high energy particle data on board Galileo (EPD) as well as plasma wave data from Ulysses and Wind. Jovian aurorae images detailed in the far UV by the Hubble Space Telescope will be correlated to in-situ radio emission spectra. In addition, we will investigate the correlation of the radio emission with published results of in situ high-speed plasma bursts. These comprehensive investigations of Galileo wave data will provide new information that will be of great importance to understanding the micro and macrophysics of the Jovian magnetosphere, and may conceivably provide a remote indicator of Jovian magnetic storms and Io volcanic activity.

E/PO Abstract:
Imagine students hearing and analyzing the radio sounds of Jupiter live, online, in the classroom! We propose to extend a recently established education and outreach project, called Radio JOVE. The project seeks to interest students in the science of radio astronomy through building their own radio telescopes, working with amateur radio operators to do radio astronomy observations, or just receiving and analyzing data from professional radio telescopes connected to the internet. Radio signals from Jupiter can only be observed at night, but we propose to create a radio telescope facility at a community college in Hawaii which can receive Jupiter radio storms during the pre-dawn hours and transmit the data live to classrooms in session in the continental United States.
