Magnetic fields at the dawn of structure formation I. The CARLA J1510+5958 proto-cluster
The episode discusses Pagliotta et al.'s paper on magnetic fields in the CARLA J1510+5958 proto-cluster at high redshift (z=1.72). Hosts review evidence of a magnetized plasma, finding field strengths significantly higher than predicted by simple models. The study uses advanced techniques to show early magnetic fields are actively amplified during structure formation.
