Abstract
The IceCube Neutrino Observatory has detected evidence for TeV neutrinos from NGC 1068, a nearby Seyfert galaxy. This discovery suggests that active galactic nuclei may play a significant role as sources of high-energy astrophysical neutrinos. Interestingly, the absence of the expected TeV gamma-ray flux indicates that these gamma-rays could be effectively obscured at their production site, with the hot coronal environment near the Seyfert galaxy’s core being a plausible location for this attenuation. Theoretical models suggest that the properties of the corona—and thus the production of neutrinos—can be inferred from the galaxy’s intrinsic X-ray luminosity. In this presentation, we report our search for neutrino emission from a sample of X-ray bright Seyfert galaxies selected from the BASS survey. We have employed a disc-corona model to predict the neutrino flux, improving the sensitivity of our search, and compared this model to the more traditional power-law flux assumption. Our stacking analysis shows a 3$\sigma$ neutrino emission signal from the catalog's collective sources.

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.
