Intra-cluster magnetic fields can be observed at the density contact discontinuity formed by cool and dense plasma running into hot ambient plasma1,2, and the discontinuity exists3 near the second-brightest galaxy4, MRCÂ 0600-399, in the merging galaxy cluster Abell 3376 (redshift 0.0461).
In contrast to typical jets10,11, MRCÂ 0600-399 shows a 90-degree bend at the contact discontinuity, and the collimated jets extend over 100 kiloparsecs from the point of the bend
High-resolution numerical simulations reveal that the ordered magnetic field along the discontinuity has an important role in the change of jet direction
Our results provide insights into the effect of magnetic fields on the evolution of the member galaxies and intra-cluster medium of galaxy clusters
