A DETAILED STUDY OF THE MOLECULAR AND ATOMIC GAS TOWARD THE γ-RAY SUPERNOVA REMNANT RX J1713.7–3946: SPATIAL TeV γ-RAY AND INTERSTELLAR MEDIUM GAS CORRESPONDENCE [PDF]
The Astrophysical Journal, 2012 RX J1713.7-3946 is the most remarkable TeV {gamma}-ray supernova remnant (SNR) that emits {gamma}-rays in the highest energy range. We have made a new combined analysis of CO and H I in the SNR and derived the total protons in the interstellar medium (ISM).

H i Self-absorption toward the Cygnus X North: From Atomic Filament to Molecular Filament
The Astrophysical Journal Letters, 2023 Using the H i self-absorption data from the Five-hundred-meter Aperture Spherical radio Telescope, we perform a study of the cold atomic gas in the Cygnus X North region.

Probing the Conditions for the H i-to-H2 Transition in the Interstellar Medium
The Astrophysical Journal, 2023 We investigate the conditions for the H i -to-H _2 transition in the solar neighborhood by analyzing H i emission and absorption measurements toward 58 Galactic lines of sight (LOSs) along with ^12 CO(1–0) (CO) and dust data. Based on the accurate column

The Evolution of the ISM in the Mildly Disturbed Spiral Galaxy NGC 4647 [PDF]
, 2006 We present matched-resolution maps of HI and CO emission in the Virgo Cluster spiral NGC 4647. The galaxy shows a mild kinematic disturbance in which one side of the rotation curve flattens but the other side continues to rise.

Dark Molecular Gas in Simulations of z~0 Disc Galaxies [PDF]
, 2018 The $\rm H_2$ mass of molecular clouds has traditionally been traced by the CO(J=1-0) rotational transition line. This said, CO is relatively easily photodissociated, and can also be destroyed by cosmic rays, thus rendering some fraction of molecular gas

AIMNet2‐NSE: A Transferable Reactive Neural Network Potential for Open‐Shell Chemistry
Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.AIMNet2‐NSE enables accurate modeling of open‐shell radical chemistry through neural spin‐charge equilibration (NSE). This machine learning interatomic potential predicts radical reaction energies, barriers, and spin‐crossing events with near‐DFT accuracy while offering five orders of magnitude computational speedup, making high‐throughput exploration ...

ASTROCHEMISTRY OF STAR FORMATION
Odessa Astronomical Publications, 2013 Star formation is one of the key processes governing the evolution of the Universe. It is accompanied by significant transformations in the chemical composition and the physical state of the interstellar medium. Combining observations in infrared and

Mapping atomic and diffuse interstellar band absorption across the Magellanic Clouds and the Milky Way [PDF]
, 2015 Diffuse interstellar bands (DIBs) trace warm neutral and weakly-ionized diffuse interstellar medium (ISM). Here we present a dedicated, high signal-to-noise spectroscopic study of two of the strongest DIBs, at 5780 and 5797 \AA, in optical spectra of 666

Evidence for the Heating of Atomic Interstellar Gas by PAHs
, 2000 We report a strong correlation between the [CII] 158 micron cooling line and the mid-infrared flux in the 5-10 micron range in a wide variety of star-forming galaxies. The mid-infrared flux is dominated by Aromatic Feature Emission (AFE), which is thought to arise from large polycyclic aromatic hydrocarbon molecules or `PAHs' and generally associated ...
