From left to right: M 82 NOEMA CO(J = 1 − 0), MIRI-F770W, and MIRI-F1130W images in cutouts of 5′×4.2′. The left panel also contains the molecular clouds identified in Section 3.2 (white contours), the centroid of the CO(J = 1 − 0) and the different regions identified in the starburst as described in Krieger et al. (2021). The inset in the left panel correspond to the NOEMA beamsize at ν = 115 GHz. The green crosses in the middle and right panels are indicate the optical center of M 82. The black contours in the middle and right panels correspond to the regions covered by the MIRI-MRS and the yellow boxes are the regions with Spitzer IRS data from Beirão et al. (2008); both are used in this work to apply a first-order continuum subtraction (see Section 3.1).
