Abstract

fetched live from OpenAlex

It is possible that supermassive black holes are ejected from centers of galaxies at high speeds. If the ejection happens in a nearby galaxy, then some black holes will travel towards us and may appear quasar-like with a blueshifted spectrum due to the Doppler effect. But quasar spectra are as a rule interpreted as having been redshifted even when there is an equally good or better case for a blueshifted spectrum. Here we study the quasars which are apparently associated with galaxies. We look for alternative identification for the spectral lines reported in the quasar spectra and offer blueshift values whenever it is consistent with the available information. We present a list of five candidates predicting the lines for future observation to confirm blueshifts. We also present a composite IR spectra which can be adjoined to existing composite spectra of lines in the optical and the UV region. We suggest that many of these objects are much less massive satellite bodies which have been ejected from nearby galaxies during binary black hole mergers.

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.
