ALMA Band 3 intensity integrated maps of the molecular species that show extended emission around IRAS 16293−2422. The 3σ level is indicated on the colorbar with a horizontal white or gray line. HC₃N 10–9 is overlaid in contours with steps of 3, 5, 7, 9, and 15σ, with σ = 10 mJy beam⁻¹ km s⁻¹. The positions of IRAS 16293 A and B are marked with a star and circle, respectively. The dashed orange lines indicate the structures identified in this work. The arrows indicate the E–W (green) and NW-SE (red) outflow directions from source A. The white ellipses in the bottom-right corner indicate the beam of the observations.
