TL;DR: In this paper, the authors presented the most extensive catalog of Faraday rotation data of compact extragalactic polarized radio sources to date, and used a recently developed algorithm that reconstructs the map and the power spectrum of a statistically isotropic and homogeneous field while taking into account uncertainties in the noise statistics.
