摘要
IceCube alert events are neutrinos with a moderate-to-high probability of
having astrophysical origin. In this study, we analyze 11 years of IceCube data
and investigate 122 alert events and a selection of high-energy tracks detected
between 2009 and the end of 2021. This high-energy event selection (alert
events + high-energy tracks) has an average probability of ≥ 0.5 to be of
astrophysical origin. We search for additional continuous and transient
neutrino emission within the high-energy events' error regions. We find no
evidence for significant continuous neutrino emission from any of the alert
event directions. The only locally significant neutrino emission is the
transient emission associated with the blazar TXS 0506+056, with a local
significance of 3 σ, which confirms previous IceCube studies. When
correcting for 122 test positions, the global p-value is 0.156 and is
compatible with the background hypothesis. We constrain the total continuous
flux emitted from all 122 test positions at 100 TeV to be below 1.2 ×
10^-15 (TeV cm^2 s)^-1 at 90
spectrum. This corresponds to 4.5
Overall, we find no indication that alert events, in general, are linked to
lower-energetic continuous or transient neutrino emission.
