Qualifying ringdown and shadow of black holes under general parametrized metrics with photon orbits
Abstract The motion of photons around black holes determines the shape of shadow and match the ringdown properties of a perturbed black hole. Observations of shadows and ringdown waveforms will reveal the nature of black holes. In this paper, we study the motion of photons in a general parametrized...
