Modeled and Observed Stratospheric Temperature Changes: Implications for Fingerprint Studies

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Changes in the vertical structure of atmospheric temperature are an important “fingerprint” of human effects on global climate. These changes are mainly driven by human‐caused increases in atmospheric levels of CO2 ${\text{CO}}_{2}$ and other well‐mixed greenhouse gases.

The Top Ten Astronomical 'breakthroughs' of the 20th century

Communicating Astronomy with the Public Journal, 2007
Astronomy was revolutionized in the 20th century. The electron was discovered in 1897 and this transformed spectroscopy and introduced plasma and magnetohydrodynamic physics and astro-chemistry.

Far-ultraviolet to Far-infrared Spectral Energy Distribution Modeling of the Star Formation History across M31

The Astronomical Journal
Our neighboring galaxy M31 has been recently surveyed at the far- and near-ultraviolet (FUV and NUV) with the UVIT telescope on AstroSat, which provides unprecedented sensitivity to young stellar populations.

Auroral Emissions on Ganymede: New Constraints on Their Electron Energy Dependence

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Auroral emissions on Ganymede provide critical insights into its magnetospheric dynamics and atmospheric composition. Using a physics‐based atmospheric model with recent atmospheric observations and laboratory measurements of electron‐impact cross‐sections, this study revisits and significantly refines the relationship between auroral emission

HARPO: a TPC as a gamma-ray telescope and polarimeter

, 2014
A gas Time Projection Chamber can be used for gamma-ray astronomy with excellent angular-precision and sensitivity to faint sources, and for polarimetry, through the measurement of photon conversion to $e^+e^-$ pairs.

Europa is Embedded in Non‐Maxwellian, Anisotropic Electron Distributions

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract In September 2022, the Juno spacecraft flew by Europa, providing new insight into the electron pitch angle and energy distributions via the Jovian Auroral Distributions Experiment electron analyzers (JADE‐E). We fit these observations with two anisotropic kappa distributions (cold and hot), accounting for spacecraft potential, which we find to

Anomalous Emission from Li- and Na-like Ions in the Corona Heated via Alfvén Waves

The Astrophysical Journal
The solar ultraviolet intensities of spectral lines originating from Li- and Na-like ions have been observed to surpass the expectations derived from plasmas with coronal approximation.
