摘要
In this study,we investigate the shadow and observational image of the Kerr-like Loop Quantum Gravity(LQG)inspired black bounce with the help of the celestial light and thin disk sources by employing the backward ray-tracing method.The results indicate that both the LQG parameterαand rotation parameter a contribute to a reduction in the shadow size.However,the influence of a is predominant,whereas that ofαis supplementary.For the accretion disk model,we extend its inner edge to the black hole's event horizon,and the motion of particles is different in the regions inside and outside the innermost stable circular orbit.We find that the correlation parameters(α,α),along with the observer’s inclination angle,affect the image’s asymmetry and the distortion of the inner shadow.As the inclination increases,the direct and lensed images diverge,creating a structure resembling a hat.Moreover,we investigate the redshift distribution of the direct lensed images of the accretion disk under different parameters and observation angles.The results show that the redshift distribution and observed intensity are evidently related to the behavior of accretion flow.These results may provide a potential approach for limiting black hole parameters,detecting quantum gravity effects,and distinguishing the LQG black hole from other black hole models.
