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 …

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

A new generation of neutrino experiments is testing the 4.7 σ anomalous excess of
electronlike events observed in MiniBooNE. This is of huge importance for particle physics …

Neutrinos are one of the most promising messengers for signals of new physics Beyond the
Standard Model (BSM). On the theoretical side, their elusive nature, combined with their …

We critically examine the ability of future neutrino telescopes, including Baikal-GVD,
KM3NeT, P-ONE, TAMBO, and IceCube-Gen2, to determine the flavor composition of high …

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 …

This Letter presents the result of a 3+ 1 sterile neutrino search using 10.7 yr of IceCube data.
We analyze atmospheric muon neutrinos that traverse the Earth with energies ranging from …

We investigate the possibilities of probing the electroweak scale seesaw scenarios such as
type-I, type-II, and type-III seesaw at e-γ and γ γ colliders. For the case of type-I seesaw, the …

We show that ATLAS, a collider detector, can measure the flux of high-energy supernova
neutrinos, which can be produced from days to months after the explosion. Using Monte …
