Quantification of Perturbation to the Daytime Lower Ionosphere From a Gamma Ray Burst Using ELF Remote Sensing

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract On 9 October 2022, a powerful gamma ray burst (GRB), GRB221009A, caused significant changes in the electron density of the lower ionosphere, as evidenced by VLF (3–30 kHz) radio wave observations. However, GRB221009A did not yield any observable signatures at the Schumann resonances (∼8, ∼14 Hz), which are also sensitive to the lower ...

Direct Observations of Acceleration of Planetary Ions From Mars' Ionosphere Through Magnetic Reconnection When IMF Rotates

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Mars lacks an intrinsic global magnetic field but possesses crustal magnetic anomalies and an atmosphere. Mars' ionosphere, resulted from interactions between Mars' atmosphere and solar radiation, directly interacts with solar wind and interplanetary magnetic field (IMF). However, the mechanisms governing ion acceleration and escape from Mars'

Exploring Magnetic Reconnection in the Collisional Ionosphere of Mars With MAVEN

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Magnetic reconnection in collisional plasmas has been widely studied in solar and laboratory plasma disciplines, but in situ measurements in space plasmas have rarely been utilized to explore this reconnection regime. Here we study collisional effects on magnetic reconnection in the Martian ionosphere by analyzing in situ data obtained by the ...
