Fig. 1


a) The continuum emission map of NGC 1068 obtained with ALMA at 349 GHz. The map is shown in color scale (in Jy beam-1 units as indicated) with contour levels 3σ, 5σ, 10σ, 15σ, 20σ, 30σ to 120σ in steps of 15σ, where 1σ = 0.14 mJy beam-1. (Δα, Δδ)-offsets are relative to the location of the phase tracking center adopted in this work: α2000 = 02h42m40.771s, δ2000 = − 00°00′47.84″. We highlight the location of the regions and components of the emission described in Sect. 3: the CND, the bar (identified by a representative isophote of the NIR K-band image of 2MASS), the bow-shock arc, and the SB ring. We also plot the edge of the eleven-field mosaic (gray dashed contour). The filled ellipse at the bottom right corner represents the beam size at 349 GHz ( at PA = 60°). b) Same as a) but zooming in on the CND region. The position of the AGN ([Δα, Δδ] [–0.9, –0.1] = [α2000 = 02h42m40.71s, δ2000 = − 00°00′47.94″]) is highlighted by the star marker. c) Continuum emission in the CND region at 689 GHz. Color scale is given in Jy beam-1 units. Contour levels are 3σ, 5σ, 7σ, and 10σ to 25σ in steps of 5σ, where 1σ = 1.95 mJy beam-1. The filled ellipse at the bottom right corner represents the beam size at 689 GHz ( at PA = 50°).
