Abstract
We present linear polarization detections of CO (3-2) line and the inferred magnetic field structure toward DR21(OH). The data is part of the SMA Legacy Project - "Filament, Magnetic Fields, and Star Formation" which is aiming at imaging dust and CO polarization at 345 GHz for a large sample of massive filaments. Our new results of CO polarizations toward DR21(OH) are in general consistent with previous BIMA results (Lai et al. 2003), but provide more detailed magnetic field structure up to 1" resolution. The CO polarizations are strongly detected and coherent in all outflow features, suggesting that the interplay between magnetic fields and outflows are important in shaping the outflow structure in DR21(OH).
