A lower limit of 50 microgauss for the magnetic field near the Galactic Centre

Crocker, Roland; Jones, David I; Melia, Fulvio; Ott, Juergen; Protheroe, Raymond

Description

The amplitude of the magnetic field near the Galactic Centre has been uncertain by two orders of magnitude for several decades. On a scale of 100 parsecs (pc), fields of 1,000 microgauss (G; refs 1g'3) have been reported, implying a magnetic energy density more than 10,000 times stronger than typical for the Galaxy. Alternatively, the assumption of pressure equilibrium between the various phases of the Galactic Centre interstellar medium (including turbulent molecular gas, the contested 'very...[Show more]
