Overview of the Ll448-mm system, as seen by ALMA. Panel a: overview of the region. The red and blue lobes of the jet are indicated by the SiO (8–7) peak intensity map. Green corresponds to the ~0.9 mm continuum. The beams of SiO (empty) and continuum (filled) are shown on the top left. Panel b: zoomed-in image of the H¹³CN (4–3) peak intensity map with continuum contours in white at [10, 30, 100]σ_cont with σ_cont = 0.25 mJy beam⁻¹. Panel c: same as b, but for CH₃OH (2_2,1,0—3_1,2,0). In panels b and c the peak of the continuum is indicated by a cross and the integrated intensity maps of the high-velocity bullets of SiO (65–75 km s⁻¹) are shown in red and blue contours (at [10, 15, 20]σ_SiO,mom0 with σ_SiO,mom0 = 6 mJy beam⁻¹ km s⁻¹).
