Core-collapse supernovae are the death of massive stars and birthplace of stellar mass compact objects, and therefore a cornerstone in both star evolution and nucleosynthesis understanding. They can also be incredible laboratories of physics at its extreme if we obtain a multi-messenger signal. In this talk, I will present a set of simulations including various microphysics changes, such as neutrino interactions with matter, equation of state, and presence of exotic particles, to study their impact on multi-messenger signals, e.g, gravitational waves and neutrino observations.
