Abstract

fetched live from OpenAlex

In a global kinematical study of NGC 5055 using high resolution Fabry-Perot interferometry, intriguing spectral line profiles have been observed in the center of the galaxy. These profiles seem to indicate a rapidly rotating disk with a radius near 365 pc and tilted 50 deg with respect to the major axis of the galaxy. In the hypothesis of a massive dark object, a naive keplerian estimate gives a mass between 10 7:2 to 10 7:5 M fi . Unfortunately the limited spectral domain of the Fabry-Perot leaves some ambiguity on the exact movement and velocity of this Hff emission. 2-D spectroscopy with a larger spectral range (eg.: TIGRE or low resolution Fabry-Perot) is thus required. 1. Introduction It is now well established that many if not all galaxies hide a massive object in their central region (Kormendy 95). Presence of such objects are usally deduced from the kinematics and photometry of the core of these galaxies. These Massive Dark Objects (MDO), tought to be black holes, produce ...

Not 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.
