Galactic Worm 123.4-1.5: A Mushroom-shaped HI Cloud
Bibliographic record
Abstract
The Dominion Radio Astrophysical Observatory's Synthesis Telescope providesthe highest resolution data (1 arcmin and 0.82 km/s) to date of an HI wormcandidate. Observed as part of the Canadian Galactic Plane Survey,mushroom-shaped GW 123.4-1.5 extends only a few hundred parsecs, contains ~10^5solar masses of neutral hydrogen, and appears unrelated to a conventional shellor chimney structure. Our preliminary Zeus-2d models use a single off-planeexplosion with a modest (~10^{51} ergs) energy input. These generic simulationsgenerate, interior to an expanding outer blast wave, a buoyant cloud whosestructure resembles the morphology of the observed feature. Unlike typicalmodel superbubbles, the stem can be narrow because its width is not governed bythe pressure behind the blast wave nor the disk scale height. Using this typeof approach it should be possible to more accurately model the thin stem andother details of GW 123.4-1.5 in the future.

Full frame distilled prediction
Teacher imitationNot 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.
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; both teacher heads agree on what is shown here.
