Insights from LHAASO and IceCube into the origin of the Galactic diffuse teraelectronvolt–petaelectronvolt emission

Nature Astronomy, 2023
High-energy diffuse gamma-ray and neutrino emission are expected from the Galactic plane, generated by hadronuclear interactions between cosmic rays and the interstellar medium.

Search for 10–1000 GeV Neutrinos from Gamma-Ray Bursts with IceCube

Astrophysical Journal, 2023
We present the results of a search for 10–1000 GeV neutrinos from 2268 gamma-ray bursts (GRBs) over 8 yr of IceCube-DeepCore data. This work probes burst physics below the photosphere where electromagnetic radiation cannot escape.

Search for Extremely-High-Energy Neutrinos and First Constraints on the Ultrahigh-Energy Cosmic-Ray Proton Fraction with IceCube.

Physical Review Letters
We present a search for the diffuse extremely-high-energy neutrino flux using 12.6 years of IceCube data. The nonobservation of neutrinos with energies well above 10 PeV constrains the all-flavor neutrino flux at 10^{18}  eV to a level of E^{2}Φ_{ν_{e ...

Explaining the PeV neutrino fluxes at KM3NeT and IceCube with quasi-extremal primordial black holes

Physical Review Letters
The KM3NeT experiment has recently observed a neutrino with an energy around 100 PeV, and IceCube has detected five neutrinos with energies above 1 PeV. While there are no known astrophysical sources, exploding primordial black holes could have produced ...

Physics potential of the IceCube upgrade for atmospheric neutrino oscillations

Physical Review D
The IceCube Upgrade is an extension of the existing IceCube Neutrino Observatory and will be deployed in the 2025-2026 austral summer. It will significantly improve the sensitivity of the detector to atmospheric neutrino oscillations.

Evolution of the IceCube data acquisition system for IceCube-Gen2

Journal of Instrumentation, 2021
IceCube-Gen2 is a future large-scale extension to the IceCube Neutrino Observatory, a cubic-kilometer-scale neutrino detector at the geographic South Pole. The IceCube data acquisition system architecture, while running stably with over 99% uptime, will be re-optimized for IceCube-Gen2 to solve design challenges with power consumption, communications ...

Demonstrating the ability of IceCube DeepCore to probe Earth’s interior with atmospheric neutrino oscillations

The European Physical Journal Special Topics
The IceCube Neutrino Observatory is an optical Cherenkov detector instrumenting one cubic kilometer of ice at the South Pole. The Cherenkov photons emitted following a neutrino interaction are detected by digital optical modules deployed along vertical ...

IceCube Search for Neutrino Emission from X-Ray Bright Seyfert Galaxies


The recent IceCube detection of TeV neutrino emission from the nearby active galaxy NGC 1068 suggests that active galactic nuclei (AGNs) could make a sizable contribution to the diffuse flux of astrophysical neutrinos.
