CO(4–3) moment-zero map (left) and rest-frame 650 μm continuum map (right) from ALMA. The colours indicate the values of the velocity-integrated flux density in Jy beam⁻¹ km s⁻¹ and the flux density in Jy beam⁻¹. Right panel: Hα map of the Cosmic Snake from SINFONI. The colour bar indicates the H_α flux (F(H_α)) in erg s⁻¹ cm⁻². The beam is displayed in white in the bottom right corners of the ALMA images.
