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…
