Black holes with a cosmological constant in bumblebee gravity

In this work, we present black hole solutions with a cosmological constant in bumblebee gravity, which provides mechanism for the Lorentz symmetry violation by assuming nonzero vacuum expectation value field. From gravitational point of view, such are spherically symmetric holes an effective and supported anisotropic energy-momentum tensor, conceived as manifestation field spacetime geometry. Then calculate shadow angular radius proposed solution positive constant. particular, our results very first relation between size.
