  Recently the quantum Oppenheimer-Snyder gravitational collapse model has been
proposed in loop quantum gravity, providing quantum-corrected Schwarzschild
spacetimes as the exterior of the collapsing dust ball. In this paper, the
quantum gravity effects on the black hole shadows in this model are studied,
and the stability of the quantum-corrected black holes is also analyzed by
calculating the quasinormal modes. It turns out that the quantum correction
always shrinks the radius of shadows, and the quantum-corrected black holes are
stable against the scalar and vector perturbations.
