Image Details
Caption: Figure 1.
The panels depict intensity images generated by galaxies from four distinct redshift bins, stacked onto the CO(2–1) Type 2 map derived from Planck data. The target bin is z = 0.4940–0.5724, but neighboring bins can also transmit redshifted CO(3–2). The beam FWHM for the Type 2 is ﹩15^{\prime} ﹩ (P. A. Ade et al. 2014a).
