A physical model for the [C II]–FIR deficit in luminous galaxies

Narayanan, Desika; Krumholz, Mark


Observations of ionized carbon at 158 μm ([CII]) from luminous star-forming galaxies at z ∼ 0 show that their ratios of [CII] to far-infrared (FIR) luminosity are systematically lower than those of more modestly star-forming galaxies. In this paper, we provide a theory for the origin of this so-called [CII] deficit in galaxies. Our model treats the interstellar medium as a collection of clouds with radially stratified chemical and thermal properties, which are dictated by the clouds’ volume and...[Show more]
