CO (left) and SiO (right) molecular outflows map of the W43-MM2 region overlaid on the 1.3 mm dust continuum map (in grayscale). The green ellipses represent the FWHM of the continuum cores convolved by the beam size. Moment 0 contours of the blueshifted wings are overlaid on the continuum map at low velocity in cyan and high-velocity in blue. Moment 0 contours of the redshifted wings are overlaid on the continuum map at low velocity in orange and high-velocity in red. CO and SiO contours are 10, 20, 40, and 80 in units of σ, with σ = 18.9, 11.0, 18.1, 6.4 mJy beam⁻¹ km s⁻¹ for CO, and σ = 4.4, 5.7, 4.5, 5.7 mJy beam⁻¹ km s⁻¹ for SiO, for cyan, blue, orange and red contours respectively. The corresponding velocity ranges are ±15–30 km s⁻¹ and ±30–45 km s⁻¹ for CO and ±10–25 km s⁻¹ and ±25–50 km s⁻¹ for SiO.
