Multiwavelength SITELLE Observations of the High-velocity System in NGC 1275
Bibliographic record
Abstract
Abstract In this paper, we present multiwavelength observations of the High-velocity System (HVS) in the Perseus Cluster taken with the SITELLE instrument at the Canada–France–Hawai’i Telescope. Using the SN 1, SN 2, and SN 3 filters, we observe emission in [ O iii ]5007, H β , [ N ii ]6548, [ N ii ]6583, and H α . By applying a Bayesian approach, we can constrain the redshift of the HVS to 0.02669 ±0.00073 . Our findings are consistent with those originally posited in A. P. Y. Yu et al., in which the authors argue that they observe evidence of ram pressure stripping, indicating that the HVS is actively interacting with the BCG of the Perseus Cluster.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
