“…To search for a possible correlation between IceCube events and supernovae, we use an unbinned maximumlikelihood method. A similar formalism was commonly used to search for transient neutrino sources by Ice-Cube [75][76][77][78][79][80][81][82][83] and other experiments [84]. The likelihood function is defined as…”

The origin of the high-energy astrophysical neutrinos discovered by IceCube remains largely unknown. Multi-messenger studies have indicated that the majority of these neutrinos come from gamma-ray-dark sources. Choked-jet supernovae (cjSNe), which are supernovae powered by relativistic jets stalled in stellar materials, may lead to neutrino emission via photohadronic interactions while the coproduced gamma rays are absorbed. In this paper, we perform an unbinned-maximumlikelihood analysis to search for correlations between IceCube's 10-year muon-track events and our SN Ib/c sample, collected from publicly available catalogs. In addition to the conventional powerlaw models, we also consider the impacts of more realistic neutrino emission models for the first time, and study the effects of the jet beaming factor in the analyses. Our results show no significant correlation. Even so, the conservative upper limits we set to the contribution of cjSNe to the diffuse astrophysical neutrino flux still allow SNe Ib/c to be the dominant source of astrophysical neutrinos observed by IceCube. We discuss implications to the cjSNe scenario from our results and the power of future neutrino and supernova observations.

“…The sensitivity could be improved by a stacked joint analysis of a large FRB sample (e.g. Aartsen et al 2018;Kheirandish et al 2019). Unfortunately, given the relatively long duration t max ∼ 3000 s for the most energetic E radio ≈ 10 44 erg bursts described above, the search becomes background-dominated after only a few bursts, after which the detector sensitivity quickly saturates.…”

The discovery of a luminous radio burst, FRB 200428, with properties similar to those of fast radio bursts (FRB), in coincidence with an X-ray flare from the Galactic magnetar SGR 1935+2154, supports magnetar models for cosmological FRBs. The burst's X-ray to radio fluence ratio, as well as the X-ray spectral shape and peak energy, are consistent with FRB 200428 being the result of an ultra-relativistic shock (powered, e.g., by an ejected plasmoid) propagating into a magnetized baryonrich external medium; the shock simultaneously generates X-ray/gamma-rays via thermal synchrotron emission from electrons heated behind the shock, and coherent radio emission via the synchrotron maser mechanism. Here, we point out that a unique consequence of this baryon-loaded shock scenario is the generation of a coincident burst of high-energy neutrinos, generated by photo-hadronic interaction of relativistic ions−heated or accelerated at the shock−with thermal synchrotron photons. We estimate the properties of these neutrino burst FRB counterparts and find that a fraction ∼ 10 −8 − 10 −5 of the flare energy (or ∼ 10 −4 − 10 −1 of the radio isotropic energy) is channeled into production of neutrinos with typical energies ∼ TeV−PeV. We conclude by discussing prospects for detecting this signal with IceCube and future high-energy neutrino detectors.
