TY - JOUR ID - 57643 AU - Konoplya, Roman PY - 2021 TI - Black holes in galactic centers: Quasinormal ringing, grey-body factors and Unruh temperature JF - Physics Letters B VL - 823 IS - December SP - "136734-1"-"136734-5" EP - "136734-1"-"136734-5" SN - 03702693 KW - NORMAL-MODES;THERMODYNAMICS;COLLAPSE UR - https://www.sciencedirect.com/science/article/pii/S0370269321006742?via%3Dihub N2 - ecently, Cardoso et al. [1] found an exact solution describing the black hole immersed in a galactic-like distribution of matter. There, the properties of gravitational radiation were studied. Here we continue analysis of properties of this geometry via consideration of the electromagnetic radiation. We calculate quasinormal modes, asymptotic tails and grey-body factors for electromagnetic radiation. In addition, we discuss the Unruh temperature for this spacetime. Estimations made in the regime which is best fitting the galaxies behavior show that influence of the environment on classical and quantum radiation around such black holes must be relatively small.
