Title: Universality in a black hole ringing: excitation factors and greybody factors, Abstract: The ringdown gravitational waves emitted by a ringing black hole areimportant for testing strong gravity physics. However, achievingprecise detection requires not only advances in observationaltechniques but also a deeper theoretical understanding of ringdown orquasinormal-mode (QNM) excitation. In this talk, I will explain theuniversality […]
