The properties of the interstellar medium in dusty, star-forming galaxies at $z\sim 2-4$: The shape of the CO spectral line energy distributions

Dominic J. Taylor, A. M. Swinbank, Ian Smail +15

The molecular gas in the interstellar medium (ISM) of star-forming galaxy populations exhibits diverse physical properties. We investigate the ${}^{12}$CO excitation of twelve dusty,…
