New askap radio-continuum surveys of the small magellanic cloud
Bibliographic record
Abstract
We present two new radio-continuum images from the Australian Square Kilometre Array Pathfinder (ASKAP) POLarisation Sky Survey of the Universe's Magnetism (POSSUM) survey in the direction of the Small Magellanic Cloud (SMC). The two new source lists produced from these images contain 36,571 radio continuum sources observed at 944 MHz and 15,227 sources at 1367 MHz, with beam sizes of 14''.5 \times 12''.2 and 8''.7 \times 8''.2 , respectively. We used the Aegean software to create these point source catalogues, and together with the previously published Meer-Karoo Array Telescope (MeerKAT) point source catalogue, we estimated spectral indices for the whole population of radio point sources in common. By cross-matching our ASKAP catalogues with the MeerKAT catalogue, we found 21,442 and 12,654 point sources in common for 944 MHz and 1367 MHz, respectively, within a 2'' region. This point source catalogue will help to further our knowledge of the SMC and highlights the power of the new generation of telescopes such as ASKAP in studying different galactic populations.
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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
