Gravitational Waves from Neutrino Asymmetries in Core-Collapse Supernovae

Understand

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.
