Organic molecules in translucent interstellar clouds. [PDF]
Orig Life Evol Biosph, 2014 Absorption spectra of translucent interstellar clouds contain many known molecular bands of CN, CH+, CH, OH, OH(+), NH, C2 and C3. Moreover, one can observe more than 400 unidentified absorption features, known as diffuse interstellar bands (DIBs), commonly believed to be carried by complex, carbon-bearing molecules.

CaFe interstellar clouds [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 A new kind of interstellar cloud is proposed. These are rare (just a few examples among ∼300 lines of sight) objects with the Ca I 4227-Å, Fe I 3720-Å and 3860-Å lines stronger than those of K I (near 7699 Å) and Na I (near 3302 Å). We propose the name ‘CaFe’ for these clouds.

Presumed Detection of C5 Molecule in the Interstellar Medium
The Astrophysical Journal, 2022 The paper suggests the presence of the carbon chain C _5 molecule in translucent, interstellar H i clouds. This species, the only five atom interstellar molecule, observable in dark, translucent clouds, seems to be observable in reasonably dense clouds ...

Molecular Clouds in the Galactic Plane from l = [59.°75, 74.°75] and b = [−5.°25, +5.°25]
The Astrophysical Journal Supplement Series, 2023 In this paper we present the distribution of molecular gas in the Milky Way Galactic plane from l = [59.75, 74.75]° and b = [−5.25, +5.25]°, using the MWISP ^12 CO/ ^13 CO/C ^18 O emission-line data.

Interstellar cloud collisions [PDF]
Monthly Notices of the Royal Astronomical Society, 1985 On decrit les resultats d'une simulation numerique en 3 dimensions de nuages interstellaires isothermes en l'absence de champs magnetiques. Les collisions, en general, ne donnent pas naissance a un ou plusieurs nuages.

Diffuse Interstellar Clouds [PDF]
Highlights of Astronomy, 1992 AbstractDiffuse clouds are interstellar objects through which starlight is not greatly extinguished. As a result, many studies rely on ultraviolet and visible measurements. The focus of this review is on spectroscopic work involving atomic and molecular lines. From these measurements, the physical and chemical makeup of the clouds is derived.

Inhomogeneity within Local Interstellar Clouds*
The Astronomical Journal, 2022 Abstract Analysis of interstellar absorption lines observed in high-resolution Hubble Space Telescope spectra of nearby stars provides temperatures, turbulent velocities, and kinetic properties of warm interstellar clouds. A new analysis of 97 interstellar-velocity components reveals a wide range of temperatures and turbulent velocities ...
