Multiwavelength finding chart of the inner ≈0.4 pc of the Galactic center observed in the K-band (red) and L-band (blue) observed with NACO (VLT). The 100 GHz observations carried out with ALMA (green) and are based on the reduced data analyzed in Moser et al. (2017). The brightest K-band (IRS7) and L-band source (IRS3) are indicated. The inset shows a zoomed-in view of the yellow box where we mark the position of Sgr A* with a green cross (×). The positions of all dusty sources analyzed in this work are shown as a magenta circle. North is up; east is to the left.
