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…

Rotating galactic black holes
Chao Zhang, Guoyang Fu, Chunyu Zhang
The galactic black hole is a supermassive black hole located at the center of a galaxy surrounded by a dark matter halo. For the first time, we establish a generic, fully-relativis…

Detecting dark matter with extreme mass-ratio inspirals
Chao Zhang, Guoyang Fu, Ning Dai
Extreme mass ratio inspirals (EMRIs), where a small compact object inspiralls onto a supermassive black hole, are excellent sources for the space-based laser interferometer gravita…
