Observation of Toroidal Magnetic Fields on 100 pc Scales in the Galactic Center
[chapter]
Proceedings of the Galactic Center Workshop 2002
We present new submillimeter polarimetric observations of the Galactic center region, made using the SPARO polarimeter that operates at the South Pole. Compared with previous submillimeter polarimetry of this region, our measurements cover much more sky area, and they imply that the molecular gas in the central few hundred pc is threaded by a large scale toroidal magnetic field. We consider this result together with radio observations that show evidence for poloidal fields in the Galactic
