... The upper panel shows a close-up of a region away from the stripes, where the black lines show tangled magnetic field lines and the red line shows an electron spiraling around one of these lines. Electrons with energies of a trillion electron volts (10^12 eV), corresponding to energies about 7 times lower than the maximum energy reached by the Large Hadron Collider (LHC), are responsible for the X-ray emission seen by Chandra. The middle panel shows a close-up of a faint stripe. ...
