Maps of various tracers in M83: material tracers (H II, H I, CO, total neutral gas, warm dust, and cold dust) and tracers of the total magnetic field (mainly its small-scale part; I6 and I13) and its ordered component (P6, P13, and P6+P13), as indicated in the upper right corner of each frame. The coordinates are given in kpc, the intensity units are arbitrary units (H II), 10²⁰ cm^-2 (H I), K km s^-1 (CO), 10²⁰ cm^-2 (gas), MJy/sterad (warm dust), Jy/beam (cold dust), μJy/beam (radio I6, I13, P6, P13, P6+P13). The axis scales are in kpc.
