Abstract

fetched live from OpenAlex

Supernova explosions of type Ia (SNe Ia) are now extensively used as "standard candles" in modern cosmology, viz. in constructing the Hubble's diagram and hence in determining various cosmological parameters. One of the most important quantities used in such analyses is the redshift of the host galaxy, which, in its turn, is determined by identifying the observed spectral lines with search lines known in the laboratory. The importance of the correct identification is therefore appreciated. The present work considers the possibility of misidentification of the observed lines. Alternative identification at higher wavelengths leads to blueshifts. Its implication in modern cosmology is discussed. A tentative model of the universe to interpret the results is proposed.

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 distilled prediction

Teacher imitation

Not 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.
