Extended Data Figure 1: ALMA continuum images of SPT0311−58.
From: Galaxy growth in a massive halo in the first billion years of cosmic history
a–d, Continuum images in ALMA bands 3 (a), 6 (b), 7 (c) and 8 (d), corresponding to rest-frame wavelengths of 380 μm, 160 μm, 110 μm and 90 μm, respectively. Note that the resolution in a is a factor of roughly ten worse than in b–d, and the displayed field of view is also larger by a factor of four. Contours at 10%, 30% and 90% of the image peak in band 6 are shown in a for scale. The ALMA synthesized beam (full-width at half-maximum) is represented as a hatched ellipse in the corner of each image.
