Abstract
Revealing star formation through increasing angular resolution in the source GI73.49+2.42(S231-IR).Top-left is the IRAS 100Jl,m image of this 5 x let L 0 embedded object 1,800 pc away, harbouring a massive protostellar core.The position ofa methanol maser is marked with a cross, and two UCRn regions with squares.Four sub-millimetre sources are associated with the IRAS source (circles), and two of these are illustrated in the higher angular resolution view to top-right.This shows the JCMT image at 450Jl,m overlaid with contours of 21Jl,m emission, as imaged with the MSX satellite.The methanol maser is coincident with the brightest sub-mm and mid-IR core.Imaging this core with Gemini at 10Jl,m at arcsecond resolution resolves it into at least four sources (bottom-right).Probing it atmilli-arcsecond resolution with the European VLBI Network (EVN) shows three clusters of methanol masers (bottom-left), with a clear 2 km/s velocity gradient over the 100 AU extent of the eastern maser cluster.Scale bars show the relative angular resolution of each frame.
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.

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
