Quantum Absorption Limit of Black Holes and the Infrared Origin of Little Red Dots (version 7)

This is Version 7.0 of November 3, 2025 (English translation of the Italian version 7.0 published on November 2, 2025). Previous versions (v1–v6) have been placed in restricted mode because they contained numerical and interpretative errors subsequently corrected.This version completely replaces previous versions, maintaining the date of first Italian publication (October 9, 2025) as official reference for scientific priority.The article develops an empirical phenomenological model to describe the chromatic evolution of Little Red Dots (LRDs) observed by JWST, interpreting it as the effect of a cutoff frequency that evolves with cosmological redshift. The work includes:– theoretical formulation of the phenomenological model,– statistical verification on JWST observational data (EIGER, FRESCO, Labbé et al.),– comparison with alternative models of obscured AGN,– discussion on cosmological implications. All previous versions (v1–v6) remain archived in the original concept DOI in Restricted Access mode, to ensure traceability, integrity and preservation of the scientific record.Author: Aldo Amoretti (2025) [email protected] of previous version 6.0: 10.5281/zenodo.17361692
