Multiwavelength, multiscale polarization maps of OMC-3. Top left: intensity and polarization map obtained with SHARC II and Hertz at 350 μm, respectively. Overlaid are polarization vectors in white and black (Houde et al. 2004, ©AAS. Reproduced with permission). Top right: total intensity, observed at 850 μm with SCUBA, is shown with overlaid polarization vectors in blue (Matthews et al. 2001, ©AAS. Reproduced with permission). Bottom left: total intensity, observed at 1.2 mm with ALMA, is shown with overlaid polarization vectors in blue. Red polarization vectors are oberserved with JVLA at 9 mm (Liu 2021, ©AAS. Reproduced with permission). Bottom right: Total intensity, observed at 214 μm with SOFIA/HAWC+, is shown with overlaid polarization vectors in blue.
