Panel a: map of the continuum-subtracted, CO(3−2) emission of PDS 456 integrated over a line width of 320 km s⁻¹. Black contours indicate the [−3,−2, 2, 3, 2ⁿ]σ significance levels (n ≥ 2 and σ = 0.013 Jy beam⁻¹ km s⁻¹) of the CO(3−2) emission. Blue contours indicate the (rest-frame) ∼340 GHz continuum [−3,−2, 2, 3, 2ⁿ]σ levels (with σ = 9.6 μJy beam⁻¹). The ALMA synthetic beam is indicated by the grey ellipse. Panel b: map of the line and continuum emitters detected in the ALMA field of view at ≳5σ.
