Abstract

We studied the shadow cast by a rotating Bardeen black hole within the framework of asymptotically safe gravity. The null geodesics were analyzed using the Hamilton Jacobi separation method to derive shadow observables. Our findings show that an increase in both the asymptotic safety parameter and the spin parameter leads to a decrease in the apparent shadow size and an increase in shadow distortion. The monopole charge of the black hole played an important role in the shadow profile. Furthermore, we compute the energy emission rate associated with varying values of the asymptotic safety parameter.
