Abstract

fetched live from OpenAlex

Black Hole Energy Boost More than 20 galaxies are known to emit photons with energies a trillion times higher than those of visible light, but it is not known where this emission originates. These galaxies are part of a class of active galactic nuclei believed to harbor supermassive black holes in their centers from which relativistic plasma jets emerge, reaching out many thousands of light years into the intergalactic medium. Acciari et al. (p. 444 , published online 2 July; see the Perspective by Begelman ) present simultaneous radio and very-high-energy γ-ray observations of the nearby active galaxy Messier 87, revealing very-high-energy flaring activity accompanied by a radio flare originating from the core of the galaxy. The findings imply that the highest energy emission from active galaxies has its origin in the immediate vicinity of the black hole.

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.
