Continuum map of the Sgr B2(N) region obtained with ALMA at 108 GHz. Contour levels (positive in black solid line and negative in dashed line) start at five times the rms noise level, σ, of 3.0 mJy/beam and double in value up to 320σ. The filled ellipse shows the synthesized beam (1.65″× 1.21″, PA = −83.4^o). The black cross represents the phase center. The red crosses mark the positions of the five hot cores embedded in Sgr B2(N). The blue crosses represent H₂O masers (McGrath et al. 2004). The dotted red circle represents the size (HPBW) of the primary beam of the 12 m antennas at 108 GHz.
