An Instrument for Isomer‐Specific Action Spectroscopy of Charged Clusters: Electronic Spectra of C 14 + and Ca@C 60 +

Chemistry–Methods, Volume 6, Issue 8, August 2026.
Disentangling spectral congestion of a mixture of isomers in gas‐phase spectroscopy is critical. We present an instrument combining ion mobility, mass spectrometry, and spectroscopy in a cryogenic 3D Paul trap to investigate the isomer‐specific charged clusters and illustrate its performance with the electronic spectra of C14+ and Ca@C60+.

Jovian Auroral Proton Precipitation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The total power of the Jovian aurora is about 1013–1014 W with ultraviolet emission observed in the Lyman and Werner bands of molecular hydrogen. X‐ray, radio, and infrared emissions have also been observed. The Jovian Auroral Distributions Experiment and the Jovian Energetic Particle Detector Instrument onboard the Juno spacecraft, orbiting ...

Cosmic Dust as a Prerequisite for the Formation of Complex Organic Molecules in Space?

The Astrophysical Journal
In cold, dense astrophysical environments dust grains are mixed with molecular ices. Chemistry in those dust/ice mixtures is determined by diffusion and reaction of molecules and radicals.

Relative Velocities between 13CO Structures within 12CO Molecular Clouds

The Astronomical Journal
Velocity fields of molecular clouds (MCs) can provide crucial information on the merger and split between clouds, as well as their internal kinematics and maintenance, energy injection and redistribution, and even star formation within clouds.

Discovery of Multiple Ultra-broad-velocity Molecular Features Associated with the W44 Molecular Cloud

The Astrophysical Journal Letters
We report the discovery of multiple compact molecular features exhibiting extremely broad velocity widths toward the W44 molecular cloud. Atacama Large Millimeter/submillimeter Array CO J = 3–2 data reveal eight “Petit-Bullets” surrounding the previously

An Ultraviolet Study of CO Chemistry in the Magellanic Clouds

The Astronomical Journal
How does molecular cloud chemistry change with metallicity? In this work, we study the relation between molecular hydrogen (H _2 ) and carbon monoxide (CO) at 1/2 and 1/5 solar metallicity using ultraviolet absorption spectroscopy obtained as part of the
