Abstract
We demonstrate that observations of the gravitational memory from core collapse supernovae at future deci-Hz interferometers enable time-triggered searches of supernova neutrinos at Mt-scale detectors. Achieving a sensitivity to characteristic strains of at least $\ensuremath{\sim}{10}^{\ensuremath{-}25}$ at $f\ensuremath{\simeq}0.3\text{ }\text{ }\mathrm{Hz}$---e.g., by improving the noise of DECIGO by one order of magnitude---will allow robust time triggers for supernovae at distances $D\ensuremath{\sim}40--300\text{ }\text{ }\mathrm{Mpc}$, resulting in a nearly background-free sample of $\ensuremath{\sim}3--70$ neutrino events per Mt per decade of operation. This sample would bridge the sensitivity gap between rare galactic supernova bursts and the cosmological diffuse supernova neutrino background, allowing detailed studies of the neutrino emission of supernovae in the local Universe.
