We have observed the linear polarization of 450 µm continuum emission from the Galactic center, using a new polarimetric detector system that is operated on a 2 m telescope at the South Pole. The resulting polarization map extends � 170 pc along the Galactic plane and � 30 pc in Galactic latitude, and thus covers a significant fraction of the central molecular zone. Our map shows that this region is permeated by large-scale toroidal magnetic fields. We consider our results together with radio… Expand

Manifestations of the Galactic Center Magnetic Field
Several independent lines of evidence reveal that a relatively strong and highly ordered magnetic field is present throughout the Galaxy’s central molecular zone (CMZ). The field within dense cloudsExpand

Effective theories of a scalar φ invariant under the internal galileon symmetry φ→ φ+ bμx μ have been extensively studied due to their special theoretical and phenomenological properties. In thisExpand
