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…

General Relativistic magneto-hydrodynamical simulations of accretion flows through traversable wormholes
Luciano Combi, Huan Yang, Eduardo Gutierrez +3
We present the first dynamical model of plasma accretion onto traversable wormholes by performing General Relativistic magneto-hydrodynamical (GRMHD) simulations of the flow on bot…
