Signatures from the observed jet power and the radiative efficiency for rotating black holes in loop quantum gravity
Zhengwei Cheng, Songbai Chen, Jiliang Jing
We investigate the radiative efficiency and jet power in the spacetime of a rotating black hole within the framework of loop quantum gravity (LQG), which includes an additional LQG…
Chaotic motion of particles in the spacetime of a Kerr black hole immersed in swirling universes
Deshui Cao, Lina Zhang, Songbai Chen +2
We investigate the motion of particles in the spacetime of a Kerr black hole immersed in swirling universes. Using the Poincaré section, fast Lyapunov exponent indicator, bifurcati…
Magnetic reconnection and energy extraction from a Konoplya Zhidenko rotating non Kerr black hole
Fen Long, Shangyun Wang, Songbai Chen +1
Recently, magnetic reconnection has attracted considerable attention as a novel energy extraction mechanism, relying on the rapid reconnection of magnetic field lines within the er…
Images of Kerr-MOG black holes surrounded by geometrically thick magnetized equilibrium tori
Zelin Zhang, Songbai Chen, Jiliang Jing
We adopt general relativistic ray-tracing (GRRT) schemes to study images of Kerr-MOG black holes surrounded by geometrically thick magnetized equilibrium tori, which belong to stea…
Constraining a disformal Schwarzschild black hole in DHOST theories with the orbit of the S2 star
Zelin Zhang, Songbai Chen, Jiliang Jing
With the observed data of the S2 orbit around the black hole Sgr A and the Markov Chain Monte Carlo method, we make a constraint on parameters of a disformal Schwarzschild blac…
