Extragalactic radio sources, IGM magnetic fields, and AGN‐based energy flows
Bibliographic record
Abstract
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 machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
