Probing Quantum Gravity effects with Extreme Mass Ratio Inspirals around Rotating Hayward Black Holes
Dan Zhang, Chao Zhang, Qiyuan Pan +2
We investigate extreme mass-ratio inspirals (EMRIs) around a rotating Hayward black hole to assess the detectability of signatures arising from quantum gravity.The quantum paramete…

Periodic orbits and their gravitational wave radiations in -metric
Chao Zhang, Tao Zhu
The -metric, also known as Zipoy-Voorhees spacetime, is a static, axially symmetric vacuum solution to Einstein's field equations characterized by two parameters: mass and the d…

The constraint on modified black holes with extreme mass ratio inspirals
Chao Zhang, Guoyang Fu, Yungui Gong
The low-energy effective action of String Theory introduces corrections to the dilaton-graviton sector, resulting in deformed black holes beyond general relativity. We analyze extr…
