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 …

The discovery of high-energy astrophysical neutrinos and the first hints of coincident
electromagnetic and neutrino emissions opened new opportunities in multi-messenger …

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 …

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 …

Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy
physics. With energies far beyond solar, supernovae, atmospheric, and accelerator …

The origins of the high-energy cosmic neutrino flux remain largely unknown. Recently, one
high-energy neutrino was associated with a tidal disruption event (TDE). Here we present …

Gamma-ray bursts (GRBs) are considered as promising sources of ultra-high-energy cosmic
rays (UHECRs) due to their large power output. Observing a neutrino flux from GRBs would …

Abstract The Ultraviolet Transient Astronomy Satellite (ULTRASAT) is scheduled to be
launched to geostationary orbit in 2027. It will carry a telescope with an unprecedentedly …

We present radio observations of 23 optically discovered tidal disruption events (TDEs) on
timescales of∼ 500–3200 days postdiscovery. We detect nine new TDEs that did not have …

We present a toy model for the thermal optical/UV/X-ray emission from tidal disruption
events (TDEs). Motivated by recent hydrodynamical simulations, we assume that the debris …
