Maps of the line transitions detected in SPT 0346-52 obtained with ALMA observations, integrated over 4σ_velocity km s⁻¹ channels. For H₂O 2₁₁ − 2₀₂ and H₂O 2₀₂ − 1₁₁ red contours are the 2, 4, 6, 8σ intervals. For CO(6−5), CO(8−7), and CO(9−8) red contours are the 5, 10, 20, 30σ intervals. The synthesized beam is shown in the bottom left corner as a red ellipse. The orange cross shows the center of the lensing galaxy.
