Exploring the origin of supermassive black holes with coherent neutrino scattering
Abstract
Collapsing supermassive stars (M ≳ 3 × 104 M ⊙) at high redshifts can naturally provide seeds and explain the origin of the supermassive black holes observed in the centers of nearly all galaxies. During the collapse of supermassive stars, a burst of non-thermal neutrinos is generated with a luminosity that could greatly exceed that of a conventional core collapse supernova explosion. In this work, we investigate the extent to which the neutrinos produced in these explosions can be observed via coherent elastic neutrino-nucleus scattering (CEνNS). Large scale direct dark matter detection experiments provide particularly favorable targets. We find that upcoming 𝒪(100) tonne-scale experiments will be sensitive to the collapse of individual supermassive stars at distances as large as 𝒪(10) Mpc.
