H2 mass, relative amount of H2, and H2 depletion time of 3D-HST GS30274 derived by adopting the following approaches; [CI]: an H2 mass based on atomic carbon; CO: an H2 mass based on the CO J = 3–2 luminosity; dust mass: an H2 mass based on the inferred dust mass from SED fitting in combination with a gas-to-dust ratio.
|Approach||H2 mass (1010M⊙)||MH2/ (MH2 + M∗)||H2 depletion time (Myr)|
|[CI]||3.0 ± 0.3||0.14 ± 0.01||140 ± 30|
|CO starburst αCO||1.7 ± 0.1||0.08 ± 0.005||80 ± 17|
|Dust mass||<0.7 ± 0.2||<0.04 ± 0.01||<30 ± 10|
