Searches for neutrinos from cosmic-ray interactions in the Sun using seven years of IceCube data

M. G. Aartsen, M. Ackermann, J. Adams, J. A. Aguilar et autres

Cosmic-ray interactions with the solar atmosphere are expected to produce particle showers which in turn produce neutrinos from weak decays of mesons. These solar atmospheric neutrinos (SAνs) have never been observed experimentally. A detection would be an important step in understanding cosmic-ray …

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

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 IceCube data are compared to solar activity and solar magnetic field models. A quantitative …

Multimessenger Gamma-Ray and Neutrino Coincidence Alerts Using HAWC and IceCube Subthreshold Data

H. A. Ayala Solares, S. Coutu, James DeLaunay, D. B. Fox et autres

Abstract The High Altitude Water Cerenkov (HAWC) and IceCube observatories, through the Astrophysical Multimessenger Observatory Network (AMON) framework, have developed a multimessenger joint search for extragalactic astrophysical sources. This analysis looks for sources that emit both cosmic neutrinos and gamma rays that …

Abbasi, R.; Ackermann, M.; Adams, J.; Aguilar, J. A.; Ahlers, M.; Ahrens, M.; Alispach, C.; Amin, N. M.; Andeen, K.; Anderson, T.; Ansseau, I.; Anton, G.; Argüelles, C.; Axani, S.; Bai, X.; Balagopal V., A.; Barbano, A.; Barwick, S. W.; Bastian, B.; …

Cosmic ray spectrum from 250 TeV to 10 PeV using IceTop

M. G. Aartsen, M. Ackermann, J. Adams, J. A. Aguilar et autres

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 the spectrum and reduces the gap in energy between previous IceTop and direct …

eV-Scale Sterile Neutrino Search Using Eight Years of Atmospheric Muon Neutrino Data from the IceCube Neutrino Observatory

M. G. Aartsen, M. Ackermann, J. Adams, J. A. Aguilar et autres

The results of a 3+1 sterile neutrino search using eight years of data from the IceCube Neutrino Observatory are presented. A total of 305 735 muon neutrino events are analyzed in reconstructed energy-zenith space to test for signatures of a matter-enhanced oscillation …

Searching for eV-scale sterile neutrinos with eight years of atmospheric neutrinos at the IceCube Neutrino Telescope

M. G. Aartsen, M. Ackermann, J. Adams, J. A. Aguilar et autres

We report in detail on searches for eV-scale sterile neutrinos, in the context of a 3+1 model, using eight years of data from the IceCube Neutrino Telescope. By analyzing the reconstructed energies and zenith angles of 305,735 atmospheric νμ and ¯νμ events …

Characteristics of the Diffuse Astrophysical Electron and Tau Neutrino Flux with Six Years of IceCube High Energy Cascade Data

M. G. Aartsen, M. Ackermann, J. Adams, J. A. Aguilar et autres

We report on the first measurement of the astrophysical neutrino flux using particle showers (cascades) in IceCube data from 2010--2015. Assuming standard oscillations, the astrophysical neutrinos in this dedicated cascade sample are dominated ($\ensuremath{\sim}90%$) by electron and tau flavors. The flux, observed …

IceCube Search for Neutrinos Coincident with Compact Binary Mergers from LIGO-Virgo’s First Gravitational-wave Transient Catalog

M. G. Aartsen, M. Ackermann, J. Adams, J. A. Aguilar et autres

Abstract Using the IceCube Neutrino Observatory, we search for high-energy neutrino emission coincident with compact binary mergers observed by the LIGO and Virgo gravitational-wave (GW) detectors during their first and second observing runs. We present results from two searches targeting emission coincident …

In-situ calibration of the single-photoelectron charge response of the IceCube photomultiplier tubes

M.G. Aartsen, M. Ackermann, J. Adams, J. A. Aguilar et autres

We describe an improved in-situ calibration of the single-photoelectron charge distributions for each of the in-ice Hamamatsu Photonics R7081-02[MOD] photomultiplier tubes in the IceCube Neutrino Observatory. The characterization of the individual PMT charge distributions is important for PMT calibration, data and Monte …

A Search for IceCube Events in the Direction of ANITA Neutrino Candidates

M. G. Aartsen, M. Ackermann, J. Adams, J. A. Aguilar et autres

Abstract During the first three flights of the Antarctic Impulsive Transient Antenna (ANITA) experiment, the collaboration detected several neutrino candidates. Two of these candidate events were consistent with an ultra-high-energy upgoing air shower and compatible with a tau neutrino interpretation. A third …
