Magnetic substructure in the northern Fermi bubble revealed by polarized microwave emission

Jones, David I; Crocker, Roland; Reich, W; Ott, Juergen; Aharonian, F

Description

We report a correspondence between giant, polarized microwave structures emerging north from the Galactic plane near the Galactic center and a number of GeV gamma-ray features, including the eastern edge of the recently discovered northern Fermi Bubble. The polarized microwave features also correspond to structures seen in the all-sky 408MHz total intensity data, including the Galactic center Spur. The magnetic field structure revealed by the Wilkinson Microwave Anisotropy Probe polarization...[Show more]
