abstract
The IceCube Neutrino Observatory is a cubic-kilometer-scale high-energy neutrino detector built into the ice at the South Pole. Construction of IceCube, the largest neutrino detector built to date, was completed in 2011 and enabled the discovery of high-energy astrophysical neutrinos. We describe here the design, production, and calibration of the IceCube digital optical module (DOM), the cable systems, computing hardware, and our methodology for drilling and deployment. We also describe the online triggering and data filtering systems that select candidate neutrino and cosmic ray events for analysis. Due to a rigorous pre-deployment protocol, 98.4% of the DOMs in the deep ice are operating and collecting data. IceCube routinely achieves a detector uptime of 99% by emphasizing software stability and monitoring. Detector operations have been stable since construction was completed, and the detector is expected to operate at least until the end of the next decade.

Proposes a new CLFV search in IceCube using cosmic-ray muons, deriving sensitivities for EFT operators and a Z' model, with comparisons to other experiments and projections for future telescopes.
Visible inelasticity in starting tracks can statistically separate tau and muon neutrino events, yielding competitive sensitivity to the tau-to-muon flux ratio with current IceCube exposures.
WavePID improves cascade purity and classification performance in low-energy IceCube events by adding single-PMT timing observables to a graph neural network morphology classifier.
No evidence for long-range neutrino interactions from a broad class of anomaly-free U(1)' symmetries is found in 8 years of IceCube DeepCore atmospheric data, producing stringent constraints on the corresponding LRI potentials and mediator parameters.
7.5-year IceCube DeepCore νμ CC data give δ_CP-free 90% CL bounds |ε_eμ|≤0.12 and |ε_eτ|≤0.18, consistent with standard interactions.
IceCube DeepCore data constrains non-unitary neutrino mixing with α33 > -0.027 at 90% CL and no evidence for deviation from unitarity.
Neutrino light curves from neutron stars may show an enhanced peak-to-plateau ratio, a density-tracing delay, and transient spectral hardening as diagnostics of hadron-quark phase transitions on 10-50 ms timescales.
A color-dipole-based Monte Carlo generator interfaced with Pythia8 predicts larger transverse momenta and higher yields of angularly separated dimuons in neutrino-proton collisions than standard Pythia.
