Description
Over the past decade, a significant number of supernovae exhibiting luminosities that exceed $10^{43}\,\mathrm{erg\, s^{-1}}$ and characterized by narrow hydrogen lines in their spectra have been discovered. These supernovae are believed to be powered by the collision of ejected material with a dense circumstellar medium (CSM). The interaction of the SNe ejecta with the CSM results in a shock wave propagating in the dense circumstellar environment, which can efficiently generate thermal UV/optical emission and accelerate protons up to PeV energies. Such protons can undergo hadronic interactions and produce neutrinos in the $1-10^{3}$ TeV energy range. I will present the connection between the neutrino signal detectable at the IceCube Neutrino Observatory and the photometric properties of the electromagnetic signals observable by optical surveys. Finally, I will discuss how detecting high-energy neutrinos can help constrain the large space of parameters characterizing interacting SNe and will outline the best follow-up strategy for upcoming multi-messenger searches from this class of objects.
