Overview of the three CMZ clouds, the 20 km s⁻¹, Sgr C, and the dust ridge cloud e by the dual-band ALMA observations. The background pseudo-color maps show the composite Spitzer 3.6, 4.5 and 8.0 μm emission. The white contours show the ATLASGAL 870 μm emission, with contour levels increasing from 3 by a step of 1 Jy beam⁻¹, up to 12 Jy beam⁻¹. The dashed yellow and orange loops outline the primary beam response of 0.2 for ALMA 3 and 1.3 mm observations, respectively. The scale bar of 1 pc is shown on the bottom right.
