In Situ Analysis of Jupiter's Broadband Kilometric Auroral Radio Emissions With Juno
Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.Abstract Among the zoo of Jovian auroral radio emissions, the broadband kilometric (bKOM) component has been the least studied. Taking advantage of Juno in situ measurements within the auroral regions, we surveyed the Juno/Waves radio observations over the 60 first orbits to identify 7 bKOM source candidates.

Ionospheric Modelling using GPS to Calibrate the MWA. II: Regional ionospheric modelling using GPS and GLONASS to estimate ionospheric gradients [PDF]
, 2016 We estimate spatial gradients in the ionosphere using the Global Positioning System (GPS) and GLONASS (Russian global navigation system) observations, utilising data from multiple GPS stations in the vicinity of Murchison Radio-astronomy Observatory (MRO).

Predictions of Auroral Electron Precipitation and Joule Heating at Uranus
Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.Abstract The precipitation of electrons and Joule heating are key processes through which energy is transferred from Uranus' magnetosphere to its upper atmosphere. These processes drive atmospheric ionization, thermospheric heating, and auroral emission at Uranus.

Ionospheric F2-layer Perturbations Observed After the M8.8 Chile Earthquake on February 27, 2010, at Long Distance from the Epicenter [PDF]
Journal of Astronomy and Space Sciences, 2017 The F2-layer critical frequency (foF2) data from several ionosondes are employed to study the long-distance effect of the M8.8 Chile Earthquake of February 27, 2010, on the F2 layer.

Characterisation of the ionosphere above the Murchison Radio Observatory using the Murchison Widefield Array [PDF]
, 2017 We detail new techniques for analysing ionospheric activity, using Epoch of Reionisation (EoR) datasets obtained with the Murchison Widefield Array (MWA), calibrated by the `Real-Time System' (RTS). Using the high spatial- and temporal-resolution information of the ionosphere provided by the RTS calibration solutions over 19 nights of observing, we ...

Ion Kinetics in Thin Current Sheets at Lunar Distances
Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.Abstract The magnetotail current sheet plays a crucial role in substorm dynamics, affecting the entire magnetosphere. Formation and reconnection of thin (ion‐gyroscale) current sheets initiate magnetospheric substorms. Theoretical models suggest that a transient, demagnetized ion population is key element of the thin current sheet configuration.

2-D model of the global ionospheric conductor connected with the magnetospheric conductors [PDF]
arXiv, 2018 A model of the ionospheric global conductor is designed. The ionospheric conductor is considered in the framework of a two-dimensional approximation based on high conductivity in the direction of the magnetic field. Under this assumption the magnetic field lines are equipotential, and the charge transfer between them is determined only by integral ...

Global-MHD Simulations using MagPIE : Impact of Flux Transfer Events on the Ionosphere [PDF]
arXiv, 2023 This study presents a recently developed two-way coupled magnetosphere-ionosphere model named MagPIE that enables the investigation of the impact of flux transfer events (FTEs) on the ionosphere. Our findings highlight the prominent role of cusp-FTE reconnection in influencing the ionosphere.
