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

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

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

Star-forming dwarf galaxies in the Virgo cluster: the link between molecular gas, atomic gas, and dust [PDF]
, 2016 We present $^{12}$CO(1-0) and $^{12}$CO(2-1) observations of a sample of 20 star-forming dwarfs selected from the Herschel Virgo Cluster Survey, with oxygen abundances ranging from 12 + log(O/H) ~ 8.1 to 8.8.

A multifrequency study of the active star forming complex NGC6357. I. Interstellar structures linked to the open cluster Pis24 [PDF]
, 2011 We investigate the distribution of the gas (ionized, neutral atomic and molecular), and interstellar dust in the complex star forming region NGC6357 with the goal of studying the interplay between the massive stars in the open cluster Pis24 and the ...

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

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 ...

[C ii] Spectral Mapping of the Galactic Wind and Starbursting Disk of M82 with SOFIA
The Astrophysical Journal, 2023 M82 is an archetypal starburst galaxy in the local Universe. The central burst of star formation, thought to be triggered by M82's interaction with other members in the M81 group, is driving a multiphase galaxy-scale wind away from the plane of the disk ...
