Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

The nuclei of most normal galaxies contain supermassive black holes, which can accrete
gas through a disk and become active. These active galactic nuclei (AGNs) can form jets that …

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 …

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 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 …

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 …

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 …

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 …

The present white paper is submitted as part of the “Snowmass” process to help inform the
long-term plans of the United States Department of Energy and the National Science …
