Fig. 2

ALMA cube showing CO(8−7) emission at two positions in the data cube: at the location of Yggdrasil and to the SW in an isolated component: Loke. Middle panel: the grey scale image of the CO(8−7) emission overlaid with the ALMA dust continuum contours. We note that the increase in noise towards the edges due to the primary beam correction. Left and right: the CO(8−7) velocity profiles for both Yggdrasil (left) and Loke (right). Surprisingly the CO(8−7) lines only have a small offset from the HeII systemic redshift. The spectra are extracted from a beam-sized area at the position of the emission, and have rmss of 1.5 mJy and 1.0 mJy respectively. Both detections are unresolved at the S/N of our data.
