Matter around Schwarzschild black holes in scalar-tensor theories: Absorption and Scattering

Qian Li, Junji Jia

We investigate the absorption and scattering by a Schwarzschild black hole in scalar--tensor theories of gravity, where the coupling between matter and the scalar field induces dif…

Radiation properties and images of loop quantum Reissner-Nordström black hole with a thin accretion disk

Qian Li, Jia-Hui Huang

We investigate the characteristics of circular motion of charged particles around loop quantum Reissner-Nordström black hole (LQRNBH) and the radiation properties and observational…

On-axis absorption and scattering of charged massive scalar waves by Kerr-Newman black-bounce spacetime

Qian Li, Qianchuan Wang, Junji Jia

We investigate the absorption and scattering of charged massive scalar waves by the Kerr-Newman black-bounce spacetime when the waves are incident along the rotation axis. Our find…

Scattering of charged massive scalar waves by Kerr-Newman black holes

Qian Li, Qianchuan Wang, Junji Jia

The scattering of charged massive scalar waves by Kerr-Newman black holes, with incidence along the equatorial plane, is investigated in this work. The differential scattering cros…

Absorption and scattering of charged scalar waves by charged Horndeski black hole

Qian Li, Qianchuan Wang, Junji Jia

We investigate the absorption and scattering of a charged massive scalar field by a charged Horndeski black hole using both the approximation or classical geometric method and the…
