Probing Jupiter's Atmosphere Through Juno Radio Occultations: Analysis of the Atmospheric Thermal Structure

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The upper layers of Jupiter's atmosphere, offering critical insights into the planet's deeper structure, are accessible through radio occultation experiments. Since July 2023, NASA's Juno extended mission has provided the first high‐resolution radio occultation measurements since the Voyager era, probing the thermal structure and composition ...

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 ...

The high-redshift Universe with the International X-ray Observatory

, 2010
We discuss some of the main open issues related to the light-up and evolution of the first accreting sources powering high redshift luminous quasars. We discuss the perspectives of future deep X-ray surveys with the International X-ray Observatory and ...

New Li Lidar Observations and Model Simulations: A Window to Anthropogenic Signatures

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract We present Li lidar observations in the mesopause region above Kühlungsborn, Germany (54°N, 12°E). The lithium layer is mainly formed by meteoric ablation. But lithium has a much higher relative abundance in space debris compared with meteoroids, making it a good indicator of anthropogenic influence in the upper mesosphere.
