Scalar-Assisted Growth of Supermassive Black Holes: Boson-Mass Windows and Observational Constraints
We study a phenomenological cosmological model of black-hole growth in which a finite baryonic reservoir and a bosonic scalar cloud feed the black hole simultaneously. The baryonic component accretes through an Eddington-like channel, while the scalar cloud transfers mass through an effective quasibound-state decay rat...
