“…By fitting the model to our −2.0 upper limit, we obtain an order-of-magnitude estimation of a lower limit on this electron-to-proton luminosity ratio, 10 −3 . This value is consistent with previously reported lower limits in the context of obscured AGN studied with IceCube [24,25].…”

Ultra-luminous infrared galaxies (ULIRGs) have total infrared luminosities that exceed 10 12 solar luminosities, making them the most luminous objects in the infrared sky. They are mainly powered by starbursts with star-formation rates exceeding 100 solar masses per year, with a possible secondary contribution from an active galactic nucleus (AGN). Both starburst regions and AGN are environments in which hadronic acceleration, and hence neutrino production, is plausible. In this work we present the results of a stacking search for high-energy neutrinos from a representative sample of 75 local ULIRGs using 7.5 years of IceCube data. No significant neutrino excess is found. We therefore report upper limits on the neutrino flux originating from these 75 ULIRGs, and extrapolate these to limits on the full ULIRG source population. We also compare these results with model predictions.

“…However, due to other uncertainties in the model, this lower limit should be regarded as an order-of-magnitude estimation. Nevertheless, we remark that this value is consistent with previous limits on provided in [15] in the context of an obscured-AGN analysis performed with IceCube [33,34].…”

With infrared luminosities IR ≥ 10 12 , Ultra-Luminous Infrared Galaxies (ULIRGs) are the most luminous objects in the infrared sky. They are predominantly powered by starburst regions with star-formation rates 100 yr −1 . ULIRGs can also host an active galactic nucleus (AGN). Both the starburst and AGN environments contain plausible hadronic accelerators, making ULIRGs candidate neutrino sources. We present the results of an IceCube stacking analysis searching for high-energy neutrinos from a representative sample of 75 ULIRGs with redshift ≤ 0.13. While no significant excess of ULIRG neutrinos is found in 7.5 years of IceCube data, upper limits are reported on the neutrino flux from these 75 ULIRGs as well as an extrapolation for the full ULIRG source population. In addition, constraints are provided on models predicting neutrino emission from ULIRGs.

They are predominantly powered by starburst regions with star-formation rates 100 𝑀 yr −1 . ULIRGs can also host an active galactic nucleus (AGN). Both the starburst and AGN environments contain plausible hadronic accelerators, making ULIRGs candidate neutrino sources. We present the results of an IceCube stacking analysis searching for high-energy neutrinos from a representative sample of 75 ULIRGs with redshift 𝑧 ≤ 0.13. While no significant excess of ULIRG neutrinos is found in 7.5 years of IceCube data, upper limits are reported on the neutrino flux from these 75 ULIRGs as well as an extrapolation for the full ULIRG source population.
