Abstract

fetched live from OpenAlex

The radial velocities of the 13 globular clusters in the Large Magellanic Cloud have a dispersion of 28 km s -1 relative to the H I rotation curve of the LMC, compared with a dispersion of 30 km s -1 with regard to the mean globular cluster velocity. This shows that, contrary to a suggestion made by Schommer et al. in 1992, one cannot yet rule out the possibility that the LMC globular clusters formed in a pressure-supported halo, rather than in a rotating disk. The globular clusters in the LMC may therefore, after all, exhibit a relationship between age and kinematics that is similar to that of the clusters in M33.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
