Angular power spectrum analysis on current and future high-energy neutrino data [PDF]

open access: yes, 2019
Astrophysical neutrino events have been measured in the last couple of years, which show an isotropic distribution, and the current discussion is their astrophysical origin. We use both isotropic and anisotropic components of the diffuse neutrino data to

Search for Neutrino Emission from Hard X-Ray AGN with IceCube [PDF]

open access: yesAstrophysical Journal
Active galactic nuclei (AGN) are promising candidate sources of high-energy astrophysical neutrinos, since they provide environments rich in matter and photon targets where cosmic-ray interactions may lead to the production of gamma rays and neutrinos ...

A Convolutional Neural Network based Cascade Reconstruction for the IceCube Neutrino Observatory [PDF]

open access: yesarXiv.org, 2021
Continued improvements on existing reconstruction methods are vital to the success of high-energy physics experiments, such as the IceCube Neutrino Observatory. In IceCube, further challenges arise as the detector is situated at the geographic South Pole

Model Constraints Based on the IceCube Neutrino Nondetection of GRB 221009A [PDF]

open access: yesAstrophysical Journal, 2022
GRB 221009A is a bright gamma-ray burst (GRB) with isotropic energy larger than 1054 erg. Its fairly low redshift makes it a promising candidate for high-energy neutrino detection.

Evidence for High-Energy Extraterrestrial Neutrinos at the IceCube Detector [PDF]

open access: yesScience, 2013
Introduction Neutrino observations are a unique probe of the universe’s highest-energy phenomena: Neutrinos are able to escape from dense astrophysical environments that photons cannot and are unambiguous tracers of cosmic ray acceleration.

Graph Neural Networks for Low-Energy Event Classification & Reconstruction in IceCube [PDF]

open access: yesarXiv.org, 2022
IceCube, a cubic-kilometer array of optical sensors built to detect atmospheric and astrophysical neutrinos between 1 GeV and 1 PeV, is deployed 1.45 km to 2.45 km below the surface of the ice sheet at the South Pole.

Search for High-energy Neutrino Emission from Galactic X-Ray Binaries with IceCube [PDF]

open access: yesAstrophysical Journal Letters, 2022
We present the first comprehensive search for high-energy neutrino emission from high- and low-mass X-ray binaries conducted by IceCube. Galactic X-ray binaries are long-standing candidates for the source of Galactic hadronic cosmic rays and neutrinos.

Estimating the impact of the QCD dynamics on the determination of the high energy astrophysical neutrino flux

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
The number of ultra-high energy neutrinos arriving at IceCube depends on the energy dependence of the astrophysical neutrino flux and neutrino cross-section. In this paper, we investigate the impact of different assumptions for the description of the QCD

Decaying Leptophilic Dark Matter at IceCube [PDF]

open access: yes, 2015
We present a novel interpretation of IceCube high energy neutrino events (with energy larger than 60 TeV) in terms of an extraterrestrial flux due to two different contributions: a flux originated by known astrophysical sources and dominating IceCube ...

Probing Pseudo-Dirac Neutrinos with Astrophysical Sources at IceCube [PDF]

open access: yesInternational Conference on Rebooting Computing, 2022
The recent observation of NGC 1068 by the IceCube Neutrino Observatory has opened a new window to neutrino physics with astrophysical baselines. In this Letter, we propose a new method to probe the nature of neutrino masses using these observations.
