Evidence for neutrino emission from X-ray Bright Seyfert Galaxies in the Southern Hemisphere using Enhanced Starting Track Events with IceCube
R. Abbasi, M. Ackermann, J. Adams +428
IceCube recently reported the observation of TeV neutrinos from the nearby Seyfert galaxy NGC~1068, and the corresponding neutrino flux is significantly higher than the upper limit…
IceCube Real-time Searches for High-energy Neutrinos Coincident with LIGO/Virgo/KAGRA Gravitational-Wave Alerts in O4a
The IceCube Collaboration, R. Abbasi, M. Ackermann +418
Gravitational-wave events from mergers of compact objects are a predicted source of high-energy neutrinos. Using data from the IceCube Neutrino Observatory, we search for neutrinos…
Sensitivity Projections for Low-Mass Dark Matter Annihilation with the IceCube Upgrade
R. Abbasi, M. Ackermann, J. Adams +412
The IceCube Upgrade, an extension designed to enhance the IceCube Neutrino Observatory's detection of neutrinos with energies between 1 GeV and 500 GeV, will markedly improve IceCu…
Search for Extremely-High-Energy Neutrinos and First Constraints on the Ultrahigh-Energy Cosmic-Ray Proton Fraction with IceCube
IceCube Collaboration, R. Abbasi, M. Ackermann +423
We present a search for the diffuse extremely-high-energy neutrino flux using years of IceCube data. The nonobservation of neutrinos with energies well above $10 \, \mathrm{…
Measurement of the inelasticity distribution of neutrino-nucleon interactions for with IceCube DeepCore
IceCube Collaboration, R. Abbasi, M. Ackermann +425
We report a study of the inelasticity distribution in the scattering of neutrinos of energy GeV off nucleons. Using atmospheric muon neutrinos detected in IceCube's sub-ar…
Search for joint multimessenger signals from potential galactic cosmic-ray accelerators with HAWC and IceCube
R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +489
The origin of high-energy galactic cosmic rays is yet to be understood, but some galactic cosmic-ray accelerators can accelerate cosmic rays up to PeV energies. The high-energy cos…
