In a recent work Kamlesh Rajpurohit (Tautenburg) and collaborators demonstrated how observations with the upgraded Very Large Array (equipped with broadband receivers) can significantly advance our knowledge about cosmic magnetism: The observation shows the spectacular Toothbrush radio relic in remarkable detail. The filamentary structures are very likely related to the distribution of magnetic fields in the cluster periphery and shed light on the origin of these fields. The observation gives a glimpse of how upcoming radio facilities will change our view of the universe!
