Time-Integrated Searches for Sub-TeV Neutrino Sources with IceCube-DeepCore
R. Abbasi, M. Ackermann, J. Adams +418
We have developed techniques for a competitive sub-TeV time-integrated neutrino search and applied it to 11.1 years of IceCube-DeepCore data. The DeepCore subarray lowers the sensi…
Search for Neutrinos from Tidal Disruption Events with IceCube
R. Abbasi, M. Ackermann, J. Adams +417
Tidal disruption events (TDEs) are theorized to produce high-energy neutrinos through photohadronic interactions between accelerated protons and multi-wavelength photons in the acc…
Searching for Extra Dimensions and Copies of the Standard Model with IceCube
R. Abbasi, M. Ackermann, J. Adams +418
The hierarchy problem remains an open question in particle physics. A number of theories that address this problem lower the fundamental scale of gravity, resulting in observable c…
Astrophysical Sensitivity Projections for the IceCube Upgrade
R. Abbasi, M. Ackermann, J. Adams +417
Embedded in the South Pole's glacial ice, IceCube detects neutrino-induced Cherenkov light using an array of digital optical modules equipped with single photomultiplier tubes (PMT…
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 +420
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…
The Delta Resonance in the Neutrino Sky
Arifa Khatee Zathul, Ke Fang, Francis Halzen +1
Recent measurements of the diffuse cosmic neutrino flux by IceCube show evidence for a spectral break at an energy near TeV. In this letter, we suggest that this featu…
The Cosmic-ray Knee as a Local Signature of Nearby PeVatrons
Ke Fang, Francis Halzen
A "knee" in the cosmic-ray spectrum, characterized by a sudden steepening of the spectral shape at PeV, may be interpreted either as a global feature of Galactic cosmic ra…
Evidence for Neutrino Emission from X-Ray-bright Active Galactic Nuclei with IceCube
R. Abbasi, M. Ackermann, J. Adams +429
Recently, IceCube reported neutrino emission from the Seyfert galaxy NGC 1068. Using 13.1 years of IceCube data, we present a follow-up search for neutrino sources in the northern…
Search for synchrotron pair echo emission following KM3-230213A
Angelina Sherman, Nestor Mirabal, David Guevel +3
The KM3NeT Collaboration has recently reported the detection of an extraordinary ultra-high-energy neutrino event with an energy of 220 PeV. Ultrahigh energy neutrinos and gamma-ra…
Cascaded Gamma-ray Emission Associated with the KM3NeT Ultra-High-Energy Event KM3-230213A
Ke Fang, Francis Halzen, Dan Hooper
A neutrino-like event with an energy of was recently detected by the KM3NeT/ARCA telescope. If this neutrino comes from an astrophysical source, or from the…
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…
Multi-messenger Emission by Magnetically Arrested Disks and Relativistic Jets of Black Hole X-ray Binaries
Riku Kuze, Shigeo S. Kimura, Ke Fang
Black hole X-ray binaries (BHXBs) are observed in various wavelengths from radio to GeV gamma-ray. Several BHXBs, including MAXI J1820+070 and Cygnus X-1, are also found to emit ul…
An NGC 1068-Informed Understanding of Neutrino Emission of the Active Galactic Nucleus TXS 0506+056
Arifa Khatee Zathul, Marjon Moulai, Ke Fang +1
We present arguments that the neutrinos observed by IceCube from the active galactic nucleus TXS 0506+056 may originate near its core and not in the blazar jet. The origin of the n…
Astroparticles from X-ray Binary Coronae
Ke Fang, Francis Halzen, Sebastian Heinz +1
The recent observation of high-energy neutrinos from the Galactic plane implies an abundant population of hadronic cosmic-ray sources in the Milky Way. We explore the role of the c…
Probing the connection between IceCube neutrinos and MOJAVE AGN
R. Abbasi, M. Ackermann, J. Adams +420
Active Galactic Nuclei (AGN) are prime candidate sources of the high-energy, astrophysical neutrinos detected by IceCube. This is demonstrated by the real-time multi-messenger dete…
