TL;DR: Radio imaging reveals a bipolar bubble structure, with an overall span of 1 degree by 3 degrees, extending above and below the Galactic plane and apparently associated with the Galactic Centre, which is postulate to be the principal source of the relativistic particles required to power the synchrotron emission of the radio filaments within and in the vicinity of the bubble cavities.
