New limits on extragalactic magnetic fields from rotation measures
TL;DR: New, statistically robust, upper limits on the strength of extragalactic magnetic fields are derived, which constrain fields with Jeans' length coherence length to be below 1.7 nG at the 2σ level, and fields coherent across the entire observable Universe below 0.65 nGs.
