EPJ Web of Conferences, 2016 Data from the IceCube Neutrino Observatory have revealed the existence of a flux of high energy neutrinos of extraterrestrial origin, which is observed in a number of analyses spanning different energy ranges, fields of view, and neutrino flavors. The current data are consistent with an isotropic, equal-flavor flux described by a simple power law ...

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 ...

Update on decaying and annihilating heavy dark matter with the 6-year IceCube HESE data
, 2019 In view of the IceCube's 6-year high-energy starting events (HESE) sample, we revisit the possibility that the updated data may be better explained by a combination of neutrino fluxes from dark matter decay and an isotropic astrophysical power-law than ...

High-energy neutrinos from blazars [PDF]
EPJ Web of ConferencesIdentifying 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 ...

Characteristics of Cherenkov Radiation in Naturally Occuring Ice
, 2016 We revisit the theory of Cherenkov radiation in uniaxial crystals. Historically, a number of flawed attempts have been made at explaining this radiation phenomenon and a consistent error-free description is nowhere available.

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.

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

Journal of Physics: Conference Series, 2007 During the last two austral summers, the first sensors of the IceCube neutrino observatory were deployed in the deep Antarctic ice, along with a surface array. We will present first results obtained using the IceCube detector, demonstrating that the performance is within the design requirements, and showing the ability to reconstruct tracks, cascades ...

The Galactic Contribution to IceCube's Astrophysical Neutrino Flux
, 2017 High energy neutrinos have been detected by IceCube, but their origin remains a mystery. Determining the sources of this flux is a crucial first step towards multi-messenger studies.

Are both BL Lacs and pulsar wind nebulae the astrophysical counterparts of IceCube neutrino events?
, 2014 IceCube has recently reported the discovery of high-energy neutrinos of astrophysical origin, opening up the PeV (10^15 eV) sky. Because of their large positional uncertainties, these events have not yet been associated to any astrophysical source.
