TL;DR: Cloud as discussed by the authors models the ionization, chemical, and thermal state of material that may be exposed to an external radiation field or other source of heating, and predicts observables such as emission and absorption spectra.

TL;DR: In this paper, the authors carried out a comprehensive far-UV survey of CO and H2 column densities along diffuse molecular Galactic sight lines and found that two power-law relationships are needed for a good fit of the entire sample, with a break located at -->log N(CO, cm −2) = 14.4, indicating a change in production route for CO in higher density gas.

TL;DR: In this article, the authors carried out a comprehensive far-ultraviolet (UV) survey of CO and H 2 column densities along diffuse molecular Galactic sight lines in order to explore in detail the relationship between CO and HO 2.

TL;DR: In this paper, the authors conducted a high-resolution mid-infrared spectroscopic investigation using Spitzer of 32 latetype (Sbc or later) galaxies that show no definitive signatures of Active Galactic Nuclei (AGN) in their optical spectra in order to search for low luminosity and embedded AGN.
