IAS Program on Particle Theory:- Testing Gravity Theories Using Higher Overtones in Black Hole Quasinormal Modes
In this talk, the speaker will introduce the parametrized black hole QuasiNorMal(QNM) ringdown formalism, a robust framework for analyzing the QNMs in systems resembling General Relativity, with a focus on higher overtones. These overtones have been shown to provide critical insights during the early ringdown phases and to exhibit heightened sensitivity to the physics near black hole horizons. Her findings indicate that larger deviations from general relativity typically appear in the quasinormal frequencies of the higher overtones. An analytical method used to understand this trend will also be discussed, including how it aligns with and expands upon previous studies. The talk will discuss the parametrized QNM formalism for higher overtones and explore its potential in testing gravity theories.
