Very-high-energy astrophysical neutrinos with IceCube

EPJ Web of Conferences, 2016
IceCube is a ≳TeV neutrino observatory operating at the South Pole. Ice-Cube has observed a flux of neutrinos of astrophysical origin, with energies beyond 2 PeV. However the sources of these neutrinos have not yet been identified.

Charged Higgs effects in IceCube: PeV events and NSIs

Journal of High Energy Physics, 2021
Extensions of the Standard Model with charged Higgs, having a non-negligible coupling with neutrinos, can have interesting implications vis-à-vis neutrino experiments.

An NGC 1068-informed Understanding of Neutrino Emission of the Active Galactic Nucleus TXS 0506+056

The Astrophysical Journal
We present arguments that the neutrinos observed by IceCube from the active galactic nucleus TXS 0506+056 may originate near its core and not in the blazar jet.

Strong constraints on non-standard neutrino interactions: LHC vs. IceCube

Journal of High Energy Physics, 2019
We find the constraints on various non-standard interactions (NSI) of neutrinos from monojet+ T searches at the Large Hadron Collider (LHC). Also, we show that the measurement of neutrino-nucleon cross-section from the observation of high energy ...

Mass and life time of heavy dark matter decaying into IceCube PeV neutrinos

Physics Letters B, 2019
Considering that the ultrahigh energy (UHE) upgoing muon neutrino events around the PeV energy region observed by the IceCube are due to the decay of superheavy dark matter to neutrinos, we constrain the mass of the decaying dark matter and its decay ...

High-energy neutrinos from blazars [PDF]

EPJ Web of Conferences
Identifying the origin of the majority of high-energy cosmic neutrinos observed by the IceCube Neutrino Observatory remains a significant challenge. Previous studies reported evidence of a spatial correlation between blazars listed in the 5th Roma-BZCat ...

Correlating High-energy IceCube Neutrinos with 5BZCAT Blazars and RFC Sources

The Astrophysical Journal Letters, 2023
We investigate the possibility that blazars in the Roma-BZCAT Multifrequency Catalogue of Blazars (5BZCAT) are sources of the high-energy astrophysical neutrinos detected by the IceCube Neutrino Observatory, as recently suggested by Buson et al. Although

IceTop: The surface component of IceCube. The IceCube Collaboration.

Nuclear Instruments and Methods in Physics Research Section A: Accelerators Spectrometers Detecto, 2013
IceTop the surface component of the IceCube Neutrino Observatory at the South Pole is an air shower array with an area of 1km2. The detector allows a detailed exploration of the mass composition of primary cosmic rays in the energy range from about 100TeV to 1EeV by exploiting the correlation between the shower energy measured in IceTop and the energy ...

Capabilities of IceCube's gamma-ray, optical and X-ray follow-up programs

EPJ Web of Conferences, 2016
The IceCube neutrino observatory is a 1 km3 detector for Cherenkov light in the ice at the South Pole. Although the presence of a diffuse astrophysical neutrino flux has been confirmed, its origin has yet to be resolved.
