NOEMA observations. The top row shows continuum images, the second row integrated CO[3−2] line emission, and the third row shows the spectra. Different columns correspond to sources A, B, and C, as labeled. The NOEMA spectrum of source A, extracted at the well-determined continuum position (S/N = 8) shows a faint 3.5σ line, at the velocity of the Lyα line at the same position. The Lyα spectra extracted over a PSF at the same location as the galaxies are shown as red dashed histograms, shifted in the plots to lower zero-level for easier comparison. The Lyα spectra are from the lower resolution, higher S/N KCWI cube. The cross in each map is ±2″ and marks the position of the phase center of the NOEMA observations.
