The Snake: A Reconnecting Coil in a Twisted Magnetic Flux Tube

Bicknell, Geoffrey; Li, J

Description

We propose that the curious Galactic center filament known as the Snake is a twisted giant magnetic flux tube, anchored in rotating molecular clouds. The MHD kink instability generates coils in the tube and subsequent magnetic reconnection injects relativistic electrons. Energy-dependent diffusion of electrons away from the coil produces a flat spectral index at large distances from it. Our fit to the existing data shows that the magnetic field of ∼0.4 mG is large compared to the ambient ∼7 μG...[Show more]
