  • Gamma-ray observations indicate that cosmic voids may host magnetic fields. Here, the authors show that relics of fields from the early Universe could be consistent with these observations if their decay is mediated by magnetic reconnection and conserves the mean square fluctuation level of magnetic helicity.
