Gravitational memory signal from neutrino self-interactions in supernova

Soumya Bhattacharya, Debanjan Bose, Indranil Chakraborty +2

Neutrinos with large self-interactions, arising from exchange of light scalars or vectors with mass $M_{\varphi }\simeq 10\mathrm{MeV}$, can play a useful role in cosmology for structure forma…
