Critical scalarization and descalarization of black holes in a generalized scalar-tensor theory
Yunqi Liu, Cheng-Yong Zhang, Qian Chen +3
We study the critical dynamics in the scalarization and descalarization in the fully nonlinear dynamical evolution in a general theory with scalar field coupling with both Gauss-Bo…
Dynamic generation or removal of a scalar hair
Yunqi Liu, Cheng-Yong Zhang, Wei-Liang Qian +2
We study dynamic processes through which the scalar hair of black holes is generated or detached in a theory with a scalar field non-minimally coupled to Gauss-Bonnet and Ricci sca…
Dynamical transitions in scalarization and descalarization through black hole accretion
Cheng-Yong Zhang, Qian Chen, Yunqi Liu +3
We present the first fully nonlinear study on the accretion of scalar fields onto a seed black hole in anti-de Sitter spacetime in Einstein-Maxwell-scalar theory. Intrinsic critica…
Shadows of magnetically charged rotating black holes surrounded by quintessence
Chengxiang Sun, Yunqi Liu, Wei-Liang Qian +1
In this work, we study the optical properties of a class of magnetically charged rotating black hole spacetimes. The black holes in question are assumed to be immersed in the quint…
Detection of scalar fields by Extreme Mass Ratio Inspirals with a Kerr black hole
Hong Guo, Yunqi Liu, Chao Zhang +3
We study extreme mass ratio inspirals occurring in modified gravity, for which the system is modeled by a small compact object with scalar charge spiraling into a supermassive Kerr…
