The exploration of the universe has recently entered a new era thanks to the multi-
messenger paradigm, characterized by a continuous increase in the quantity and quality of …

High-energy cosmic rays are observed indirectly by detecting the extensive air showers
initiated in Earth's atmosphere. The interpretation of these observations relies on accurate …

A high-energy neutrino event detected by IceCube on 22 September 2017 was coincident in
direction and time with a gamma-ray flare from the blazar TXS 0506+ 056. Prompted by this …

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large
number of particles along the beam collision axis, outside of the acceptance of existing LHC …

The observation of electromagnetic radiation from radio to γ-ray wavelengths has provided a
wealth of information about the Universe. However, at PeV (10 15 eV) energies and above …

A supermassive black hole, obscured by cosmic dust, powers the nearby active galaxy NGC
1068. Neutrinos, which rarely interact with matter, could provide information on the galaxy's …

The IceCube Neutrino Observatory has established the existence of a high-energy all-sky
neutrino flux of astrophysical origin. This discovery was made using events interacting within …

INTRODUCTION Neutrinos are tracers of cosmic-ray acceleration: electrically neutral and
traveling at nearly the speed of light, they can escape the densest environments and may be …

We present a measurement of the high-energy astrophysical muon–neutrino flux with the
IceCube Neutrino Observatory. The measurement uses a high-purity selection of650k …

This Letter presents the results from pointlike neutrino source searches using ten years of
IceCube data collected between April 6, 2008 and July 10, 2018. We evaluate the …
