Estimating the sensitivity of the IceCube Upgrade to probe the interior of the Earth using atmospheric neutrino oscillations
The IceCube Collaboration, R. Abbasi, M. Ackermann +421
The IceCube Upgrade is a densely instrumented central region of the IceCube Neutrino Observatory, deployed during the 2025-26 polar season. It will reduce the detector's energy thr…
High-energy neutrino emission from the Milky Way
R. Abbasi, M. Ackermann, J. Adams +440
The Milky Way hosts astrophysical objects that accelerate cosmic rays to energies beyond the reach of terrestrial particle accelerators. It remains a longstanding goal to locate th…
Ultrahigh-energy cosmogenic neutrino emissions in the high-redshift universe
Shigeru Yoshida, Maximilian Meier
The James Webb Space Telescope (JWST) revealed a large population of active galactic nuclei (AGN) with redshifts greater than five. We show that if they emit ultrahigh-energy proto…
Improved measurements of the TeV-PeV extragalactic neutrino spectrum from joint analyses of IceCube tracks and cascades
R. Abbasi, M. Ackermann, J. Adams +424
The IceCube South Pole Neutrino Observatory has discovered the presence of a diffuse astrophysical neutrino flux at energies of TeV and beyond using neutrino induced muon tracks an…
Evidence for a Spectral Break or Curvature in the Spectrum of Astrophysical Neutrinos from 5 TeV--10 PeV
R. Abbasi, M. Ackermann, J. Adams +424
We report improved measurements of the all flavor astrophysical neutrino spectrum with IceCube by combining complementary neutrino samples in two independent analyses. Both analyse…
Probing neutrino emission at GeV energies from compact binary mergers with the IceCube Neutrino Observatory
IceCube Collaboration, R. Abbasi, M. Ackermann +415
The advent of multi-messenger astronomy has allowed for new types of source searches by neutrino detectors. We present the results of the search for 0.5-100 GeV astrophysical neutr…
