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…
High-Energy Neutrino Tomography of the Earth's Interior with IceCube
The IceCube Collaboration, R. Abbasi, M. Ackermann +417
The Earth's interior reflects its geological evolution, from accretion to present-day dynamics. Its structure drives the geodynamo in the outer core, generating the magnetic field…
WavePID: Low-energy flavor identification using single-PMT time series in IceCube
R. Abbasi, The IceCube Collaboration, M. Ackermann +438
The IceCube Neutrino Observatory, a cubic-kilometer detector at the South Pole, identifies neutrino flavor through event morphology. Sparse photon detection makes this classificati…
Observation of In-ice Askaryan Radiation from High-Energy Cosmic Rays
ARA Collaboration, N. Alden, S. Ali +74
We present the first experimental evidence for in-ice Askaryan radiation -- coherent charge-excess radio emission -- from high-energy particle cascades developing in the Antarctic…
Modeling the refractive index profile n(z) of polar ice for ultra-high energy neutrino experiments
S. Ali, P. Allison, S. Archambault +67
We have developed an in-situ index of refraction profile n(z) for cold polar ice, using the transit times of radio signals broadcast from an englacial transmitter to 2-5 km distant…
