Left: H₂ column density image of G345.88-1.10 on a log scale at a spatial resolution of 18″ derived from Herschel data at 160 and 250 μm. The hub morphology has been highlighted by the skeleton of the filament network present in the region. Right: corresponding Herschel dust temperature map. The black box indicates the region of interest for this paper which is presented in more detail in Fig. 3.
