H<scp>i</scp>Observations of the Local Group Dwarf WLM
Bibliographic record
Abstract
We present Australia Telescope Compact Array mosaic H I imaging of the Local Group dwarf irregular galaxy WLM. We find an integrated flux of 149 Jy km s -1 and a total H I mass of (3.2 ± 0.3) × 10 7 M ⊙ . The major axis of the H I is aligned with the stellar component of the galaxy. The overall H I distribution is relatively smooth at our resolution and has a double-peaked central core. One of these peaks is aligned with a region found to have extinction that is internal to WLM, and we take this as possible evidence of a large molecular gas complex in the southern half of the galaxy. The other H I peak is in close proximity to the brightest H II regions. WLM's overall velocity field is consistent with rigid-body rotation. A rotation curve is derived, and we find a total dynamical mass of (3.00 ± 0.80) × 10 8 M ⊙ . We also performed a wide-field search, 38' in radius, for H I companions or evidence of recent interactions (e.g., tidal tails) and found no detections to an H I mass limit of M H I > 8.4 × 10 5 M ⊙ .

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.
