Search for Astrophysical Neutrinos from 1FLE Blazars with IceCube
R. Abbasi, M. Ackermann, J. Adams +379
The majority of astrophysical neutrinos have undetermined origins. The IceCube Neutrino Observatory has observed astrophysical neutrinos but has not yet identified their sources. B…
Improved Characterization of the Astrophysical Muon-Neutrino Flux with 9.5 Years of IceCube Data
R. Abbasi, M. Ackermann, J. Adams +376
We present a measurement of the high-energy astrophysical muon-neutrino flux with the IceCube Neutrino Observatory. The measurement uses a high-purity selection of ~650k neutrino-i…
A search for neutrino emission from cores of Active Galactic Nuclei
R. Abbasi, M. Ackermann, J. Adams +376
The sources of the majority of the high-energy astrophysical neutrinos observed with the IceCube neutrino telescope at the South Pole are unknown. So far, only a gamma-ray blazar w…
Combining Maximum-Likelihood with Deep Learning for Event Reconstruction in IceCube
Mirco Hünnefeld
The field of deep learning has become increasingly important for particle physics experiments, yielding a multitude of advances, predominantly in event classification and reconstru…
Observation of Cosmic Ray Anisotropy with Nine Years of IceCube Data
Frank McNally, Rasha Abbasi, Paolo Desiati +7
The IceCube Observatory has collected over 577 billion cosmic-ray induced muon events in its final configuration from May 2011 to May 2020. We used this data set to provide an unpr…
Multi-messenger searches via IceCube's high-energy neutrinos and gravitational-wave detections of LIGO/Virgo
Doğa Veske, Raamis Hussain, Zsuzsa Márka +5
We summarize initial results for high-energy neutrino counterpart searches coinciding with gravitational-wave events in LIGO/Virgo's GWTC-2 catalog using IceCube's neutrino trigger…
Study of Mass Composition of Cosmic Rays with IceTop and IceCube
Paras Koundal, Matthias Plum, Julian Saffer
The IceCube Neutrino Observatory is a multi-component detector at the South Pole which detects high-energy particles emerging from astrophysical events. These particles provide us…
Testing the AGN Radio and Neutrino correlation using the MOJAVE catalog and 10 years of IceCube Data
Abhishek Desai, Justin Vandenbroucke, Alex Pizzuto
On 22 September 2017, IceCube reported a high-energy neutrino event which was found to be coincident with a flaring blazar, TXS 0506+056. This multi-messenger observation hinted at…
Search for GeV Neutrino Emission During Intense Gamma-Ray Solar Flares with the IceCube Neutrino Observatory
R. Abbasi, M. Ackermann, J. Adams +364
Solar flares convert magnetic energy into thermal and non-thermal plasma energy, the latter implying particle acceleration of charged particles such as protons. Protons are injecte…
A search for time-dependent astrophysical neutrino emission with IceCube data from 2012 to 2017
IceCube Collaboration, R. Abbasi, M. Ackermann +361
High-energy neutrinos are unique messengers of the high-energy universe, tracing the processes of cosmic-ray acceleration. This paper presents analyses focusing on time-dependent n…
Measurements of the Time-Dependent Cosmic-Ray Sun Shadow with Seven Years of IceCube Data -- Comparison with the Solar Cycle and Magnetic Field Models
M. G. Aartsen, R. Abbasi, M. Ackermann +376
Observations of the time-dependent cosmic-ray Sun shadow have been proven as a valuable diagnostic for the assessment of solar magnetic field models. In this paper, seven years of…
Cosmic Ray Spectrum from 250 TeV to 10 PeV using IceTop
IceCube Collaboration
We report here an extension of the measurement of the all-particle cosmic-ray spectrum with IceTop to lower energy. The new measurement gives full coverage of the knee region of th…
Time-integrated Neutrino Source Searches with 10 years of IceCube Data
IceCube Collaboration, M. G. Aartsen, M. Ackermann +357
This paper presents the results from point-like neutrino source searches using ten years of IceCube data collected between Apr.~6, 2008 and Jul.~10, 2018. We evaluate the significa…
