Horizonless Astrophysical Black Holes as a Galaxy-Quenching Feedback Driver
The proposal that ultra-compact objects lacking an event horizon (astrophysical black holes) quench star formation in galaxies more effectively than classical event-horizon black holes. By computing accretion-disk radiative flux in a general spherically symmetric metric, the model shows a horizonless compact object launches disk winds far more readily and strongly than a black hole, because energy that would otherwise cross the horizon is instead available to power outflows. This yields more efficient quasar- and radio-mode AGN feedback, explaining long-term quenching (supermassive ABHs) and short-term quenching (stellar-mass ABHs).
