Beschreibung
Core-collapse supernovae (CCSN) emit neutrinos and antineutrinos of all flavors with distinct luminosities and energy spectra. As neutrinos propagate through the dense and anisotropic stellar interior, their interactions with the surrounding medium introduce several characteristic energy scales -- including neutrino self-interactions, neutrino-electron forward scattering, and vacuum mixing -- which shape their flavor evolution and ultimately determine the flavor-dependent signal observed on Earth. In this talk, I will discuss slow and fast flavor conversion mechanisms and investigate how, under what conditions and to what extent the spatially inhomogeneous neutrino-electron forward scattering influences these flavor conversion processes, CCSN dynamics, and the resulting neutrino signal. I will also present analytical strategies to incorporate these effects into supernova hydrodynamical simulations while maintaining computational efficiency, and explore their signatures using realistic supernova matter profiles at different stages of evolution.
