Left: overview of the Sgr B2 complex in ALMA 3 mm dust continuum from Ginsburg et al. (2018). From south to north, the coloured stars indicate the positions of G+0.633, Sgr B2(S), Sgr B2(M), Sgr B2(N), and G+0.693. The white stars denote all of the dense hot cores characterised so far towards Sgr B2(S) and Sgr B2(DS) (Jeff et al. 2024). The dashed golden square represents the extension of Sgr B2(DS) as traced by Meng et al. (2019) VLA continuum maps at 4 GHz. The blue and green rectangles indicate the area shown in the right panels. Right: 0th-moment map of HNCO 404 − 303 towards G+0.693 (upper panel) and G+0.633 (lower panel), computed through the MOPRA observations of the GC by Jones et al. (2012) and measured in TA∗ units. Contours are added at 98, 90, 80, 70, 60, 50, 40, 30, and 20% of the maximum. The beam is shown in the bottom left (∼38′). -- Astronomy and Astrophysics
