Dense Molecular Gas: A Sensitive Probe of Stellar Feedback Models
Philip F. Hopkins, Desika Narayanan, Norman Murray +1
We show that the mass fraction of GMC gas (n>100 cm^-3) in dense (n>>10^4 cm^-3) star-forming clumps, observable in dense molecular tracers (L_HCN/L_CO(1-0)), is a sensitive probe…
