Left: multi-phase build-up of the ISM of Haro 11, composed of a compact H ii region (C_HII) in red, a dense fragmented PDR (C_PDR) in blue, a diffuse medium of lower ionisation (D) in yellow, and warm dust in the inner region (represented as dots close to the starburst). Right: diagram of the contribution of each individual ISM phase to the global emission of the MIR and FIR lines. Red color corresponds to C_HII, blue to C_PDR, with possible enhancement in the [C ii] (and [Si ii]) lines when considering magnetic fields (hashed blue, C_B), and yellow from the diffuse ionised medium (D_l), also with possible contribution from a diffuse neutral phase (hashed yellow, D_h).
