Identifying Modified Theories of Gravity Using Binary Black-hole Ringdown

Explore how binary black-hole ringdown signals can be used to identify and test modified theories of gravity in this conference talk from the International Centre for Theoretical Sciences. Learn about the theoretical framework for analyzing gravitational wave signatures that could reveal deviations from Einstein's general relativity, focusing specifically on the ringdown phase of binary black-hole mergers. Discover the methodologies and techniques used to extract information about alternative gravitational theories from these cosmic events, and understand how current and future gravitational wave detectors can serve as laboratories for fundamental physics. Examine the implications of modified gravity theories for our understanding of spacetime and the universe, while gaining insights into the cutting-edge research being conducted at the intersection of gravitational wave astronomy and theoretical physics.
