First all-flavor search for transient neutrino emission using 3-years of IceCube DeepCore data

Abstract: Since the discovery of a flux of high-energy astrophysical neutrinos, searches for their origins have focused primarily at TeV-PeV energies. Compared to sub-TeV searches, high-energy searches benefit from an increase in the neutrino cross section, improved angular resolution on the neutrino direction, and a reduced background from atmospheric neutrinos and muons. However, the focus on high energy does not preclude the existence of sub-TeV neutrino emission where IceCube retains sensitivity. Here we present the… Show more

“…We calculate the number of signal events using the latest allflavor effective areas for GRECO selection (Abbasi et al 2022) and through-going muon neutrinos (Abbasi et al 2021b) in IceCube. The values of sig  for different models are shown in Figure 2, on the left.…”

“…19, enabling IceCube to continue to perform analyses competitive with planned Northern observatories [601,611]. Lower-energy data sets targeting astrophysical transients with all-flavor full-sky coverage have recently given new limits on sub-TeV astrophysical phenomena [600,612] and an expanded data set, shown in Fig. 18, will soon open a new channel for multi-messenger analyses [599].…”

“…Optical Cherenkov neutrino telescopes, such as the IceCube Neutrino Observatory, typically have optimal sensitivities TeV, which is significantly higher than one could expect from even the most optimistic models for cosmic-ray acceleration in novae. Some previous searches for sub-TeV neutrino sources have been performed by Super-Kamiokande (Thrane et al 2009;Abe et al 2018) as well as by IceCube (Aartsen et al 2016;Abbasi et al 2022a), but these analyses have targeted other classes of astrophysical transients.…”
