报告摘要:
In this talk, I will first show the dynamical properties of a Horndeski hairy black hole under both external fields and gravitational odd perturbations. Then I will show photon rings, shadow and lensing effects of the hairy black hole illuminated by thin accretions, which exhibit distinguishable features from those of Schwarzschild black hole in general relativity.
