A particular form of Saturn kilometric radiation at the low end of its spectrum
Fischer, G.; Taubenschuss, U.; Pisa, D.; Lamy, L.; Wu, S.; Ye, S.-Y.; Jackman, C. M.; O'Dwyer, E. (2023)We studied the spectral morphology of Saturn kilometric radiation (SKR) with the Cassini RPWS (Radio and Plasma Wave Science) instrument and found a particular structure at very low frequencies which we nicknamed "caterpillar" ... -
Auroral emissions and inner magnetospheric dynamics during Earth's response to the 28th October 2021 Coronal Mass Ejection
Waters, J. E.; Jackman, C. M.; Whiter, D. K.; Fogg, A. R.; Lamy, L.; Carter, J. A.; Coxon, J. C.; Fryer, L.; Louis, C. K.; Paxton, L. J.; Briand, C.; Cecconi, B.; Issautier, K.; Bonnin, X.; Gallagher, P. (Dublin Institute for Advanced Studies, 2023)On 28th October 2021 the Sun released a large Coronal Mass Ejection (CME) in Earth's direction. An X1.0 class solar flare and a rare ground level enhancement (GLE) were observed, along with bright solar radio bursts. Here ... -
Latitudinal distribution of auroral kilometric radiation based on Polar spacecraft observations
Louis, C. K.; Smith, K. D.; Jackman, C. M.; Fogg, A. R.; Waters, J. E.; O'Dwyer, E. P.; Granroth, L. (2023)Auroral Kilometric Radiation (AKR) is a terrestrial radio emission that occurs above the poles. It is produced by the cyclotron maser instability at frequencies close to the electron cyclotron frequency (proportional to ... -
A method for the automatic detection of solar type III radio bursts with Wind/Waves
Waters, J. E.; Jackman, C. M.; Fogg, A. R.; Louis, C.; Lamy, L.; Briand, C.; Bonnin, X.; Maksimovic, M.; Murphy, P. C.; Cecconi, B.; Issautier, K.; Whiter, D. K. (2023)Solar type III radio bursts have a characteristic signature in frequency-time dynamic spectrograms and provide important insight into the dynamics of the Sun and solar wind. Direct physical inferences of the source electrons ... -
Predictions for Uranus-moons radio emissions and comparison with Voyager 2/PRA observations
Jackman, C. M.; Cecconi, B.; Hess, S. L. G.; Louis, C. K.; Lamy, L. (2023)Jupiter's and Saturn's moons are known to induce auroral emission in the Ultraviolet wavelengths. At Jupiter, the moons Io, Europa and Ganymede are also responsible for powerful decametric radio emissions, driven by the ... -
Selection of low frequency extensions of Saturn kilometric radiation
O'Dwyer, E. P.; Jackman, C. M.; Domijan, K.; Lamy, L.; Louis, C. K. (2023)Saturn's Kilometric Radiation is an auroral emission that occurs between a few kHz to 1.2 MHz, and peaks in the frequency range 100-400 kHz (Kaiser et al., 1984). It was detected quasi-continuously by Cassini from its ... -
Testing the relationship between Saturn's ENA and narrowband radio emissions
Kinrade, J.; Badman, S. V.; Paranicas, C.; Jackman, C. M.; Louis, C. K.; O'Dwyer, E. P. (2023)Saturn's kilometric radiation (SKR) and Energetic Neutral Atom (ENA) emissions are important remote diagnostics of the planet's magnetospheric dynamics, intensifying during periods of global-scale plasma injection, and ... -
Using crossings of Saturn's magnetospheric boundaries to explore the link between upstream conditions and radio emission
Jackman, C. M.; O'Dwyer, E. P.; Louis, C. K.; Fogg, A. R.; Waters, J. E.; Lamy, L. (2023)Saturn has several components to its radio emission which can change in response to varying solar wind and magnetospheric conditions. These radio components include the Saturn Kilometric Radiation (SKR), a cyclotron maser ...
