We present a broadband spectrum of gravitational waves from core-collapse
supernovae (CCSNe) sourced by neutrino emission asymmetries for a series of
full 3D simulations. The associated gravitational wave strain probes the
long-term secular evolution of CCSNe and small-scale turbulent activity and
provides insight into the geometry of the explosion. For non-exploding models,
both the neutrino luminosity and the neutrino gravitational waveform will
encode information about the spiral SASI. The neutrino memory will be
detectable for a wide range of progenitor masses for a galactic event. Our
results can be used to guide near-future decihertz and long-baseline
gravitational-wave detection programs, including aLIGO, the Einstein Telescope,
and DECIGO.
