no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

Abstract I review the interconnections between extragalactic radio sources and extragalactic magnetic fields in large‐scale structure. I focus on energy flows and magnetic fields arising from AGN‐powered radio sources. A new combined Faraday rotation (RM) and galaxy count analysis is described which provides the first Faraday RM test for magnetic field strengths in regions of local cosmological large‐scale structure. I also describe both recent and new results that probe intergalactic magnetic fields via faint synchrotron radiation at the lowest detectable levels. Evidence for the cosmologically early generation of significant magnetic fields in galaxy systems is briefly reviewed, including initial results of a new global RM probe out to redshifts greater than 3. In the course of reviewing these new results, I comment on some desirable specifications of next‐generation instruments. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
