ASTROPHYSICAL BLACK HOLES AS A POTENTIAL SOURCE OF A SUBDOMINANT DARK-SECTOR COMPONENT Energy screening, historical population-integrated throughput, and a phenomenological source-term framework Preprint Abstract We examine whether energy released outside the horizons of accreting astrophysical black holes could produce a stable, subdominant dark-sector component. Production from the exterior plasma and extraction of rotational energy require explicit couplings. Energy that has crossed a classical event horizon cannot simply reappear outside because its products are invisible; any proposed horizon-mediated alternative needs a…
