We study the cosmic MeV neutrino background from accretion disks formed during collapsars and the coalescence of compact-object mergers. We provide updated estimates, including detection rates, of relic neutrinos from collapsars, as well as estimates for neutrinos that are produced in mergers. Our results show that diffuse neutrinos detected at HyperK would likely include some that were emitted from binary neutron-star mergers. The collapsar rate is uncertain, but at its upper limit relic neutrinos from these sources would provide a significant contribution to the Cosmic Diffuse Neutrino Background.

  1. Prospects for Neutrino Observation and Mass Measurement from Binary Neutron Star Mergers

    hep-ph 2025-11 conditional novelty 6.0 of 10

    Binary neutron star merger neutrinos will require a megaton-scale detector and decades of operation to detect, but a single detected neutrino could set a sub-eV (~0.1 eV) limit on the lightest neutrino mass via gravit...

  2. Impact of Neutrino Flavour Conversion on the Diffuse Neutrino Background from Neutrino-dominated Accretion Flows

    astro-ph.HE 2026-08 conditional novelty 5.0 of 10

    Neutrino flavour conversion strongly suppresses the diffuse neutrino background from neutrino-dominated accretion flows if the neutrino mass ordering is inverted, leaving a detectable signal only in the normal ordering.

  3. Neutrinos from explosive transients at the dawn of multi-messenger astronomy

    astro-ph.HE 2024-12 unverdicted

    This review summarizes the state of neutrino emission from supernovae and neutron-star mergers, covering thermal and high-energy signals, flavor conversion, and multi-messenger detection strategies.
