Symmergent gravity is the $R+R^2$ gravity theory which emerges in a way
restoring gauge symmetries broken explicitly by the ultraviolet cutoff in
effective field theories. To test symmergent gravity we construct novel black
hole solutions in four dimensions, and study their shadow in the vacuum as well
as plasma medium. Our detailed analyses show that the horizon radius, Hawking
temperature, Bekenstein-Hawking entropy, shadow angular radius, and photon
deflection angle are sensitive probes of the symmergent gravity and particle
spectrum of the underlying quantum field theory.
