HAWC+/SOFIA Observations of OMC-1

HAWC+/SOFIA has made polarimetric and photometric observations of the massive star formation region, OMC-1, at 53, 89, 154, and 214 microns. The inferred magnetic field direction at the longer wavelengths is globally in agreement with previous measurements supporting the idea that the cloud is undergoing magnetically-regulated star formation. In the 53 and 89 micron bands, the polarization around the BN object differs from that of the longer two wavelengths and displays a similar bipolar symmetry as the BN/KL explosion indicating that the magnetic field energy density is less than the kinetic energy density of the explosion near the center of this region. We also find a correlation between the degree of polarization and the local dispersion in polarization angle that lends evidence that depolarization with increasing unpolarized intensity is likely due to magnetic field geometry as opposed to variations in grain alignment efficiency.
