Left: overview of the structures in the inner 4.8 pc of the GC. Shown in orange: CND (CN(2–1), Martín et al. 2012); blue: minispiral (100 GHz continuum, this work); and green star: Sgr A*. The abbreviations are as follows: NE lobe for northeastern lobe, SW lobe for southwestern lobe, SE for southern extension, NEE for northeastern extension, CNA for CND-northern Arm, NEA for northeastern arm, NA for northern arm, WA for western arc, EA for eastern arm, and EB for eastern bridge. The new defined regions are southern extension west (SEW), southern extension east (SEE), Triop, and V-cloud. Right: overview of the stars and filaments Paumard et al. (2006), Viehmann et al. (2006), Mužić et al. (2007) mentioned in this work, demonstrated for the inner 20′′ (0.8 pc) on a Very Large Telescope (VLT/NACO) NIR L’ (3.8 μm) emission map (Sabha, priv. comm., here: arbitrary units).
