Description
IceCube has detected a diffuse flux of high-energy neutrinos of astrophysical origin. Although several neutrino sources have been identified, they contribute only a small fraction of the total flux, leaving most of its origin unresolved. We present a novel approach to modelling a diffuse high-energy neutrino flux from star-forming activity using SIMBA, a state-of-the-art cosmological simulation that incorporates the dynamical evolution of galaxies. Our methodology combines a phenomenological framework for high-energy neutrino production from active star-forming regions with this large-scale ($100$ Mpc h$^{-1}$) hydrodynamical simulation. This approach allows us to trace neutrino emission from star-forming activity through cosmic history. We present predictions for the contribution of star-forming activity to the diffuse neutrino flux and outline the underlying modelling framework.
