Has LIGO Detected Primordial Black Hole Dark Matter? -- Tidal Disruption in Binary Black Hole Formation
Yuan Gao, Xiaojia Zhang, Meng Su
The frequent detection of binary mergers of black holes (BHs) by the Laser Interferometer Gravitational-Wave Observatory (LIGO) rekindled researchers' interest…
Strong gravitational lensing of a 4-dimensional Einstein-Gauss-Bonnet black hole in homogeneous plasma
Xing-Hua Jin, Yuan-Xing Gao, Dao-Jun Liu
We investigate the strong gravitational lensing of spherically symmetric black holes in the novel Einstein-Gauss-Bonnet(EGB) gravity surrounded by unmagnetised plasma medium. The d…
Analytically approximated scalarized black holes and their thermodynamic stability
Yuan-Xing Gao, Dao-Jun Liu
It is recently shown that, besides the Schwarzshcild black hole solution, there exist also scalarized black hole solutions in some Einstein-scalar-Gauss-Bonnet theories. In this pa…
Scalar perturbations on the background of Kerr black holes in the quadratic dynamical Chern-Simons gravity
Yuan-Xing Gao, Yang Huang, Dao-Jun Liu
We study the scalar perturbation on the background of a Kerr black hole in the dynamical Chern-Simons modified gravity with a quadratic coupling between the scalar field and Chern-…
