Article Synopsis
  • A supermassive black hole in the galaxy NGC 1068, hidden by cosmic dust, is believed to power its active core, and neutrinos might help us understand this.
  • Researchers analyzed data from the IceCube neutrino detector from 2011 to 2020 to detect neutrinos from various gamma-ray sources, including NGC 1068.
  • They discovered an excess of high-energy neutrinos from NGC 1068, indicating a significant connection to the galaxy's activity, and these neutrinos were found to be much more abundant than previously measured gamma rays from the same source.

We report a search for nonstandard neutrino interactions (NSI) using eight years of TeV-scale atmospheric muon neutrino data from the IceCube Neutrino Observatory. By reconstructing incident energies and zenith angles for atmospheric neutrino events, this analysis presents unified confidence intervals for the NSI parameter ε_{μτ}. The best-fit value is consistent with no NSI at a p value of 25.

We present an all-sky 90% confidence level upper limit on the cosmic flux of relativistic magnetic monopoles using 2886 days of IceCube data. The analysis was optimized for monopole speeds between 0.750c and 0.
