Polarized image of a Schwarzschild black hole with a thin accretion disk as photon couples to Weyl tensor

Abstract We have studied polarized image of a Schwarzschild black hole with an equatorial thin accretion disk as photon couples to Weyl tensor. The birefringence of photon originating from the coupling affect the black hole shadow, the thin disk pattern and its luminosity distribution. We also analy...

The stronger effect of the coupling on the observed polarized vector appears only in the bright region close to black hole.
