From Diffuse Gas to Dense Molecular Cloud Cores [PDF]
Space Science Reviews, 2020 Molecular clouds are a fundamental ingredient of galaxies: they are the channels that transform the diffuse gas into stars. The detailed process of how they do it is not completely understood. We review the current knowledge of molecular clouds and their substructure from scales $\sim~$1~kpc down to the filament and core scale.

Diffuse Atomic and Molecular Clouds
Annual Review of Astronomy and Astrophysics, 2006Diffuse interstellar clouds have long been thought to be relatively devoid of molecules, because of their low densities and high radiation fields. However, in the past ten years or so, a plethora of polyatomic molecules have been observed in diffuse clouds, via their rotational, vibrational, and electronic transitions.

Two populations of diffuse molecular clouds
Astrophysical Journal, 1988 Sensitive CO and (C-13)O measurements have been made toward a number of diffuse clouds and high-latitude molecular clouds (HLCs). The results suggest that the diffuse clouds are an inhomogeneous class of objects which can be separated according to their CO column density.

A search for diffuse gamma rays with energies above 1014 eV from molecular clouds in the galaxy [PDF]
AIP Conference Proceedings, 1994 Diffuse gamma‐rays from molecular clouds are excellent tracers of cosmic rays in the galaxy over a wide range of energies. For example, diffuse emission detected by EGRET already places significant constraints on the spectrum and origin of galactic ...

What causes the ionization rates observed in diffuse molecular clouds? The role of cosmic ray protons and electrons [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 International audienceCosmic rays are usually assumed to be the main ionization agent for the interior of molecular clouds, where UV and X-ray photons cannot penetrate. Here, we test this hypothesis by limiting ourselves to the case of diffuse clouds and

AMBIPOLAR DIFFUSION AND TURBULENT MAGNETIC FIELDS IN MOLECULAR CLOUDS
Modern Physics Letters A, 2011We review the introduction and development of a novel method for the characterization of magnetic fields in star-forming regions. The technique is based on the comparison of spectral line profiles from coexistent neutral and ion molecular species commonly detected in molecular clouds, sites of star formation.

Shocks in Diffuse and Dense Molecular Clouds
1988The chemistry in postshock gas in interstellar clouds is particularly rich because reactions which are endothermic or which have activation barriers proceed more readily in gas heated to T ≳ 103 K than in cooler gas; in particular, the formation of sulfur-bearing and silicon-bearing species is efficient in postshock regions.
