Optical depth estimates and effective critical densities of dense gas tracers in the inner parts of nearby galaxy discs
High critical density molecular lines like HCN(1-0) or HCO+(1-0) represent our best tool to study currently star-forming, dense molecular gas at extragalactic distances. The optical depth of these lines is a key ingredient to estimate the effective density required to excite emission. However, const...
