  This work is devoted to the exploration of shadow cast and center of mass
energy in the background of a 4-dimensional charged Gauss-Bonnet AdS black
hole. On investigating particle dynamics, we have examined BH's metric
function. Whereas, with the help of null geodesics, we pursue to calculate the
celestial coordinates and the shadow radius of the black hole. We have made use
of the hawking temperature to study the energy emission rate. Moreover, we have
explored the center of mass energy and discussed its characteristics under the
influence of spacetime parameters. For a better understanding, we graphically
represent all of our main findings. The acquired result shows that both charge
and AdS radius ($l$) decrease the shadow radius, while the Gauss-Bonnet
coupling parameter $\alpha$ increases the shadow radius in AdS spacetime. On
the other hand, both $Q$ and $\alpha$ result in diminishing the shadow radius
in asymptotically flat spacetime. Finally, we investigate the energy emission
rate and center of mass energy under the influence of $Q$ and $\alpha$.
