Description
The theory of core-collapse Supernovae (SNe) has been developed during the past five decades, and nowadays can be considered a field mature enough to be studied at the interface of gravitational, particle, nuclear and numerical physics. Recent realistic 3D SN simulations have revealed that successful explosions can be self-triggered only by accounting for the heating by neutrinos anisotropically emitted from the protoneutron star (PNS) and large neutrino-driven convective instabilities. Nevertheless, both of these phenomena are characterized by a non-vanishing quadrupole momentum, which could generate a large emission of gravitational waves (GW) in the range of frequencies $1-10^3$ Hz. In this talk, I will discuss the main features of the expected GW signal from both anisotropic neutrino emission and matter motions, showing that it might be in the reach of current and future GW detectors for a future Galactic SN event. In particular, I will argue that, in case of a direct detection, the GW signal could provide a lot of information regarding the different phase of the explosion, neutrino emission and PNS oscillation modes. In many cases, this analysis results to be complementary to what we can learn from a direct detection of the SN neutrino burst.
