(author), Kennicutt, R. C. (author), Kreckel, K. (author), Rigopoulou, D. (author), van der werf, p (author), Wilson, C (author)The [C ii] 158 μm fine-structure line is the brightest emission line observed in local star-forming galaxies. As a major coolant of the gas-phase interstellar medium, [C ii] balances the heating, including that due to far-ultraviolet photons, which heat the gas via the photoelectric effect. However, the origin of [C ii] emission remains...journal article 2017

The [C ii]/TIR ratio ranges from above 1% to below 0.1% in the sample, with a mean value of 0.48 ± 0...journal article 2017
