英文摘要: Quantum gravity corrections to accretion onto a Schwarzschild black hole are considered in the context of the asymptotically safe scenario. The possible positions of the critical points are discussed and the general conditions for critical points are obtained. The explicit expressions for the matter density compression and the temperature profile, both below the critical radius and at the event horizon, are derived. For polytropic matter, we determine the corrected temperature and the integrated flux resulting from quantum gravity effects at the event horizon, which might be considered as a test of the asymptotically safe scenario.
