We use wavelet transform-based multi-scale analysis to identify localized structures in pseudorapidity space in high-energy nuclear collisions of 
O–Ag/Br and 
S–Ag/Br at 60A GeV and 200A GeV, respectively. Our analysis specifically focuses on ring-like and jet-like events and incorporate simulation models such as FRITIOF, UrQMD, and AMPT. Comparing experimental and simulated data, it is evidently found that the data obtained through different models reproduce the coarse features of the high-energy experiments but with minute differences. The absence of certain irregularities in the simulated data may be due to higher statistics in the simulations resulting in smoother distributions. We also observed distinct differences between experimentally observed ring-like and jet-like events, confirming their different origins. Our findings suggest that this approach is one of the most promising way to investigate the complex dynamics of high-energy nuclear collisions.
