Quadratic Mode Couplings in Rotating Black Holes and Their Detectability
Neev Khera, Sizheng Ma, Huan Yang
Quadratic quasinormal modes encode fundamental properties of black hole spacetimes. They are also one of the key ingredients of nonlinearities of General Relativity in the ringdown…
Universal gravitational self-force for a point mass orbiting around a compact star
Xuefeng Feng, Huan Yang
In this work, we study the gravitational back-reaction (i.e., the "self-force") of a point mass moving around a non-rotating, compact star on a circular orbit. We find that the add…
The excitation of quadratic quasinormal modes for Kerr black holes
Sizheng Ma, Huan Yang
The excitation of quadratic quasinormal modes is an important nonlinear phenomenon for a Kerr black hole ringing at a specific linear mode. The amplitude of this second-order effec…
Superradiant clouds may be relevant for close compact object binaries
Ao Guo, Jun Zhang, Huan Yang
Bosonic fields (within suitable mass range) may be collectively generated by rotating black holes through the black hole superradiance process. The resulting black hole is surround…
