CO excitation of normal star forming galaxies out to z=1.5 as regulated by the properties of their interstellar medium

E. Daddi, H. Dannerbauer, D. Liu +15

We investigate the CO excitation of normal star forming disk galaxies at z=1.5 using IRAM PdBI observations of the CO[2-1], CO[3-2] and CO[5-4] transitions for 4 galaxies, includin…
