Neutrinos with large self-interactions arising from exchange of light scalars or vectors with mass Mϕ≃10  MeV can play a useful role in cosmology for structure formation and solving the Hubble tension. It has been proposed that large self-interactions of neutrinos may change the observed properties of supernova like the neutrino luminosity or the duration of the neutrino burst. In this paper, we compare the gravitational wave memory signal arising from supernova neutrinos.
