First Observation of the Second Harmonic of Upper Band Chorus Waves Linking to Slow Z‐Mode

Geophysical Research Letters
The Z‐mode, comprising fast and slow branches, is a ubiquitous electromagnetic wave in planetary magnetospheres. While fast Z‐mode generation is attributed to electron cyclotron maser instability, the slow Z‐mode mechanism remains unresolved.

3D Reconstruction of DART Ejecta at Dimorphos Reveals an Anisotropic, Filamentary Structure

The Planetary Science Journal
We present a 3D reconstruction of the ejecta plume generated by the DART impact on Dimorphos based on LUKE images acquired by LICIACube. Using adaptive histogram equalization and geometric coregistration from multiple vantage points, we identified and ...
