| Abstract : | Gravitational waves have opened a new observational window to the Universe, allowing us to explore the inner regions of the most relativistic baryonic objects, such as neutron and proto-neutron stars (PNSs). These regions, which are inaccessible to electromagnetic observations, can be scrutinized using modern gravitational wave interferometers. However, deciphering the complex message encoded in the gravitational wave signal produced during and after the collapse of massive stars presents a significant challenge, especially in comparison to the signals generated by compact object mergers. The intricate physics of collapsed stellar cores is further complicated by the presence of magneto-hydrodynamic instabilities, introducing a high degree of stochasticity. Therefore, the optimization of tools to extract physically meaningful information is of paramount importance. In this study, we conduct a comprehensive comparison of various time-frequency transforms applied to gravitational wave signals generated by state-of-the-art three-dimensional neutrino-magnetohydrodynamic simulations.
