The IceCube-Gen2 Collaboration -- Contributions to the 39th International Cosmic Ray Conference (ICRC2025)

R. Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

IceCube-Gen2 is a planned next-generation neutrino observatory at the South Pole that builds upon the successful design of IceCube. Integrating two complementary detection technologies for neutrinos, optical and radio Cherenkov emission, in combination with a surface array for cosmic-ray air shower detection, …

Probing the PeV Region in the Astrophysical Neutrino Spectrum using $ν_μ$ from the Southern Sky

R. Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

IceCube has observed a diffuse astrophysical neutrino flux over the energy region from a few TeV to a few PeV. At PeV energies, the spectral shape is not yet well measured due to the low statistics of the data. This analysis probes …

Search for an eV-Scale Sterile Neutrino Using Improved High-Energy νμ Event Reconstruction in IceCube

R. Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

This Letter presents the result of a 3+1 sterile neutrino search using 10.7 yr of IceCube data. We analyze atmospheric muon neutrinos that traverse the Earth with energies ranging from 0.5 to 100 TeV, incorporating significant improvements in modeling neutrino flux and …

Search for a light sterile neutrino with 7.5 years of IceCube DeepCore data

R. Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

We present a search for an eV-scale sterile neutrino using 7.5 years of data from the IceCube DeepCore detector. The analysis uses a sample of 21,914 events with energies between 5 and 150 GeV to search for sterile neutrinos through atmospheric muon …

Erratum: “A Search for IceCube Sub-TeV Neutrinos Correlated with Gravitational-wave Events Detected By LIGO/Virgo” (2023, ApJ, 959, 96)

Rasha U. Abbasi, M. Ackermann, James H. Adams, Sanjib Kumar Agarwalla et autres

The LIGO/Virgo collaboration published the catalogs GWTC-1, GWTC-2.1, and GWTC-3 containing candidate gravitational-wave (GW) events detected during its runs O1, O2, and O3. These GW events can be possible sites of neutrino emission. In this paper, we present a search for neutrino …

Evidence for neutrino emission from the nearby active galaxy NGC 1068

R. Abbasi, M. Ackermann, J. Adams, J. A. Aguilar et autres

A supermassive black hole, obscured by cosmic dust, powers the nearby active galaxy NGC 1068. Neutrinos, which rarely interact with matter, could provide information on the galaxy's active core. We searched for neutrino emission from astrophysical objects using data recorded with the …

Simulation and sensitivities for a phased IceCube-Gen2 deployment

Brian A. Clark, Rasha Abbasi, M. Ackermann, Jenni Adams et autres

The IceCube Neutrino Observatory opened the window on high-energy neutrino astronomy by confirming the existence of PeV astrophysical neutrinos and identifying the first compelling astrophysical neutrino source in the blazar TXS0506+056. Planning is underway to build an enlarged detector, IceCube-Gen2, which will …

The SkyLLH framework for IceCube point-source search

Tomas Kontrimas, Rasha Abbasi, Markus Ackermann, Jenni Adams et autres

Hypothesis tests based on unbinned log-likelihood (LLH) functions are a common technique used in multi-messenger astronomy, including IceCube's neutrino point-source searches. We present the general Python-based tool "SkyLLH", which provides a modular framework for implementing and executing log-likelihood functions to perform data …

Searching for High Energy Neutrinos from Magnetars with IceCube

M. Ackermann, Jenni Adams, Juanan Aguilar, M. Ahlers et autres

Magnetars are neutron stars with very strong magnetic fields on the order of 1013 to 1015 G. Young magnetars with oppositely-oriented magnetic fields and spin moments may emit high-energy (HE) neutrinos from their polar caps as they may be able to accelerate …
