H<scp>i</scp>Detection of Two Dwarf S0 Galaxies in Nearby Groups: ESO 384-016 and NGC 59
Bibliographic record
Abstract
A H I survey of 10 dE/dS0 galaxies in the nearby Sculptor and Centaurus A groups was made using the Australia Telescope Compact Array. The observed galaxies have accurate distances derived by Jerjen et al. using the surface brightness fluctuation technique. Their absolute magnitudes are in the range -9.5 > M B > -15.3. Only two of the 10 galaxies were detected at our detection limit (∼1.0 × 10 6 M ⊙ for the Centaurus group and ∼5.3 × 10 5 M ⊙ for the Sculptor group): the two dS0 galaxies ESO 384-016 in the Centaurus A group and NGC 59 in the Sculptor group, with H I masses of × 10 6 and × 10 7 M ⊙ , respectively. Those two detections were confirmed using the Green Bank Telescope. These small H I reservoirs could fuel future generations of low-level star formation and could explain the bluer colors seen at the center of the detected galaxies. Similar to what is seen with the Virgo dwarf ellipticalss, the two objects with H I appear to be on the outskirts of the groups.

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.
