Abstract: We discuss the low-frequency gravitational wave signals from three state-of-the-art three-dimensional core-collapse supernova models produced with the chimera supernova code. We provide a detailed derivation of the gravitational wave signal sourced from the anisotropic emission of neutrinos and provide the total (fluid-sourced and neutrino-sourced) gravitational waves signal generated in our models. We discuss the templatability of this low-frequency signal, which is useful for future work involving matched filtering for signal detection and parameter estimation.
