Large, highly organized radio structures near the galactic centre

Abstract

A radio map of the galactic centre made at a wavelength of 20 cm with the Very Large Array telescope reveals that most of the radio emission arising within 50 pc of the galactic centre is not associated with ionizing radiation from recently formed stars. Rather, the large-scale geometry and the measured polarization of the radio emission strongly suggest that the nonthermally emitting gas is arranged along magnetic structures indicative of a substantial poloidal component to the magnetic field in the central region of the Galaxy.
