Three-colour composite, multi-wavelength view of the central region in NGC253. Blue, red, and green show the X-ray emission from Lopez et al. 2023, optical [NII] data from Cronin et al. in prep., and CO(3-2) emission from Leroy et al. (2018), respectively. The B field lines and the emission of Stokes I emission of our ALMA Band 4 data (upper panel) and Band 7 data (lower panel) are also shown as white vectors and yellow contours, respectively. The vectors are displayed every two pixels and only where PI/σPI > 3. The grey contours correspond to [5, 7, 10, 30, 100]×σI. The red arrow marks the position of the molecular south-western streamer. The white rectangle on the upper panel marks the region shown on Fig. 8. The SSCs are marked as white stars and labelled following the notation of Leroy et al. (2018). The yellow contour mark the position of the SC region defined in Section 4.
