Abstract

fetched live from OpenAlex

Abstract The 2MASS survey is used to trace the shape of the external Galaxy where an asymmetric warp is detected. We use the Besançon Galaxy model to quantify the parameters of the stellar warp in the outer part of the Galaxy. The shape of the stellar warp is then compared with previous results and with similar structures in gas and dust. We find new constraints on the stellar warp, which is shown to be not symmetrical on both sides of the Galaxy, similar to observations of H I. The positive longitude side is found to be easily modeled with a normal warp but with a slope significantly smaller than the slope seen in the H I warp. At negative longitudes, the warp presents peculiarities which are not well reproduced by any model, even with a 3‐Fourier mode warp. Finally, comparing with the warp seen in the dust, it seems to follow a slope intermediate between the gas and the stars. (© 2008 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.
