Spherically Symmetric Fluid Simulations of Black Hole Accretion in Self-Interacting Dark Matter Halos
Zhe Meng, Tan Chen, Bocheng Zhu +4
We investigate black hole accretion in self-interacting dark matter (SIDM) halos using a self-gravitating fluid model with thermal conduction. We develop a robust one-dimensional s…
Periodic Gravitational Lensing with Oscillating Boson Stars
Xing-Yu Yang, Tan Chen, Rong-Gen Cai
We show that oscillating (real-scalar) boson stars generically host an \emph{oscillating radial caustic}. Sources near this caustic cross it every half period, thereby producing pe…
Modulations of Gravitational Waves due to Non-static Gravitational Lenses
Xing-Yu Yang, Tan Chen, Rong-Gen Cai
Gravitational waves (GWs) offer a new observational window into the universe, providing insights into compact objects and cosmic structures. Gravitational lensing, commonly studied…
Quasinormal modes of gravitational perturbation for uniformly accelerated black holes
Tan Chen, Rong-Gen Cai, Bin Hu
We first show that the master equations for massless perturbations of accelerating rotating black holes can be transformed into the Heun's equation. The quasinormal modes of the bl…
Gravitational microlensing by dressed primordial black holes
Rong-Gen Cai, Tan Chen, Shao-Jiang Wang +1
The accretion of dark matter around the primordial black holes (PBHs) could lead to the formation of surrounding minihalos, whose mass can be several orders of magnitude higher tha…
