In Einstein-{\AE}ther theory, the Lorentz symmetry is locally broken in the high-energy regime due to the presence of the{\AE}ther field. This shall leave significant imprint on astronomical observation. In this paper, we investigate the optical appearance of two types of the static and spherically symmetric black holes in Einstein-{\AE}ther theory. Via Euler-Lagrange equation, we obtain the equations of motion of the photon and calculate the total deflection angle of the photon trajectory around the black hole. By classifying the light rays with the total number of orbits, we study the effects of coupling constants on the direct image, lensing ring, and photon ring. The features of the light trajectories are also investigated by comparing with the Einstein-{\AE}ther theory and general relativity. Moreover, we also show the explicit optical appearance of black holes surrounded by thin disk emissions with three characteristic emitted models. The results indicate that the direct image gives the main contribution to the total flux, and the lensing ring just gives a very small contribution, whereas the role of the photon ring is negligible. The optical appearances are also found to significantly rely on these coupling constants.

Schwarzschild Black Holes Immersed in Born-Infeld Magnetic Fields and Their Observational Signatures
Numerically solving full Born-Infeld magnetic fields around a Schwarzschild black hole makes meridional photon orbits prolate and elongates the black hole shadow along the polar axis at high inclination.

Black hole solutions with a linear equation of state in Ho\v{r}ava gravity and Einstein--{\ae}ther theory
Three families of static spherically symmetric black-hole solutions in Hořava/Einstein-æther theory are generated from chosen linear equations of state, yielding RN-like, extremal degenerate-horizon, and repulsive-pot...

Shadows and accretion disk images of charged rotating black hole in modified gravity theory
Ray-traced images of the Kerr-Newman-MOG black hole show that the MOG parameter α enlarges and rounds the shadow, and its effect beats that of the electric charge Q.

Testing Extended Theories of Gravity via Black Hole Photon Rings
For Konoplya-Zhidenko deformed Schwarzschild black holes, epsilon controls photon sphere, shadow, and photon ring size while a2 and b2 are observationally degenerate, and EHT data constrain epsilon to about -0.09 to 0...

Testing Einstein Maxwell Power-Yang-Mills Hair via Black Hole Photon Rings
For the p=1/2 Einstein-Maxwell power-Yang-Mills black hole, increasing the hair parameter Q_YM shrinks the horizon, photon sphere, ISCO, shadow, and photon ring, an effect equivalent to a mass shift in Reissner-Nordström.
