Limits on Neutrino Emission from GRB 221009A from MeV to PeV using the IceCube Neutrino Observatory
R. Abbasi, M. Ackermann, J. Adams +382
Gamma-ray bursts (GRBs) have long been considered a possible source of high-energy neutrinos. While no correlations have yet been detected between high-energy neutrinos and GRBs, t…
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…
VERITAS and multiwavelength observations of the Blazar B3 2247+381 in response to an IceCube neutrino alert
Atreya Acharyya, Colin B. Adams, Priyadarshini Bangale +494
While the sources of the diffuse astrophysical neutrino flux detected by the IceCube Neutrino Observatory are still largely unknown, one of the promising methods used towards under…
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{…
Characterization of the Three-Flavor Composition of Cosmic Neutrinos with IceCube
R. Abbasi, M. Ackermann, J. Adams +429
Neutrinos oscillate over cosmic distances. Using 11.4 years of IceCube data, the flavor composition of the all-sky neutrino flux from 5\,TeV--10\,PeV is studied. We report the firs…
Time-Integrated Southern-Sky Neutrino Source Searches with 10 Years of IceCube Starting-Track Events at Energies Down to 1 TeV
R. Abbasi, M. Ackermann, J. Adams +423
In the IceCube Neutrino Observatory, a signal of astrophysical neutrinos is obscured by backgrounds from atmospheric neutrinos and muons produced in cosmic-ray interactions. IceCub…
