Naritaka Oshita (Special Postdoctoral Researcher, iTHEMS) has revealed the "universal combination" of vibration patterns of black holes that are most easily excited from theoretical calculations.
This research result is expected to contribute to the measurement of the weight and rotation speed of black holes by observational data of space-time ripples (gravitational waves) propagating immediately after the merger of a binary black hole, and to the precise test of Einstein’s general theory of relativity.
