Probing Dark Matter with Gravitational Waves: Spin-Modulated Dephasing from Black Holes in Halos
Guoyang Fu, Yunqi Liu, Jian-Pin Wu +2
We develop a novel analytical framework for constructing axisymmetric black hole spacetimes sourced by dark matter (DM) halos. Applying this to extreme mass ratio inspirals (EMRIs)…
Detecting the secondary spin with extreme mass ratio inspirals in Scalar-Tensor theory
Hong Guo, Chao Zhang, Yunqi Liu +3
In this paper, we investigate the detectability of secondary spin in the extreme mass ratio inspirals system within a modified gravity model coupled with a scalar field. The centra…
Magnetic-induced Spontaneous Scalarization in Dynamcial Chern-Simons Gravity
Shao-Jun Zhang, Bin Wang, Eleftherios Papantonopoulos +1
In the framework of the dynamical Chern-Simons gravity, we study the scalar field perturbations of the Reissner-Nordström-Melvin spacetime, which describes a charged black hole per…
Dirac observables in the 4-dimensional phase space of Ashtekar's variables and spherically symmetric loop quantum black holes
Geeth Ongole, Hongchao Zhang, Tao Zhu +2
In this paper, we study a proposal put forward recently by Bodendorfer, Mele and Münch and Garc\'ıa-Quismondo and Marugán, in which the two polymerization parameters of spherically…
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…
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…
