Panel a: ArTéMiS 350 μm dust continuum map of the NGC 6334 region (André et al. 2016) and panel b: blow-up of the field imaged here with ALMA, with the skeleton of the velocity-coherent fiber-like structures identified in the N2H+ data cube overlaid as colored curves (see Sect. 3.3.2 and Table 3). In panel b, dark blue squares mark 3.1 mm compact sources associated with N2H+ emission and embedded in F-1, light blue squares 3.1 mm sources associated with N2H+ emission andembedded in F-2, yellow squares 3.1 mm sources embedded in F-1, F-2, or F-3 and marginally detected in only one N2H+ channel, black squares 3.1 mm sources associated with N2H+ emission in the main filament but not embedded in any N2H+ velocity-coherent structure, and white squares 3.1 mm sources in the main filament not associated with any N2H+ emission. The red triangles indicate 3.1 mm compact sources possibly contaminated by free–free emission.
