Statistical Analysis of Spectral and Chemical Correlations Between Black Holes and Quasars: Toward the Identification of a Non-Conventional Astrophysical Mechanism

This work presents a statistical investigation of spectral, chemical, and physical correlations in astronomical objects based on publicly available FITS spectra. The analysis includes spectral correlation measurements, chemical emission line strength comparisons (Hα, Hβ, [OIII], [NII]), redshift-based radial distance estimation, polynomial regression modeling, and residual statistical analysis. All computations were performed using a fully reproducible Python pipeline. The repository contains the complete analysis notebook and associated scripts required to replicate the results. The raw spectral FITS files are not included due to storage constraints but are available from the author upon reasonable request.
