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…
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…
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…
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…
