Are we observing a NSC in course of formation in the NGC 4654 galaxy?

We use direct \(N\)-body simulations to explore some possible scenarios for the future evolution of two massive clusters observed toward the center of NGC\,4654, a spiral galaxy with mass similar to that of the Milky Way. Using archival HST data, we obtain the photometric masses of the two clusters, \(M=3\times 10^5\) M\(_\odot\) and \(M=1.7\times 10^6\) M\(_\odot\), their half-light radii, \(R_{\rm eff}\sim4\) pc and \(R_{\rm eff} \sim 6\) pc, and their projected distances from the photometric center of the galaxy (both \(
