Starburst galaxies, which are known as 'reservoirs' of high-energy cosmic-rays, can
represent an important high-energy neutrino 'factory'contributing to the diffuse neutrino flux …

High-Energy and Ultra-High-Energy Neutrino Astrophysics

DFG Fiorillo - Universe, 2024 - mdpi.com
The origin of high-energy cosmic rays, and their behavior in astrophysical sources, remains
an open question. Recently, new ways to address this question have been made possible …

Pulsar TeV halos explain the diffuse TeV excess observed by Milagro

T Linden, BJ Buckman - Physical Review Letters, 2018 - APS
Milagro observations have found bright, diffuse TeV emission concentrated along the
galactic plane of the Milky Way. The intensity and spectrum of this emission is difficult to …

Are starburst galaxies a common source of high energy neutrinos and cosmic rays?

C Lunardini, GS Vance, KL Emig… - Journal of Cosmology …, 2019 - iopscience.iop.org
A recent analysis of cosmic ray air showers observed at the Pierre Auger Observatory
indicates that nearby starburst galaxies (SBGs) might be the cause of∼ 10% of the Ultra …

Flavor Anisotropy in the High-Energy Astrophysical Neutrino Sky

B Telalovic, M Bustamante - arXiv preprint arXiv:2310.15224, 2023 - arxiv.org
High-energy astrophysical neutrinos, with TeV--PeV energies, offer unique insight into
astrophysics and particle physics. Their incoming directions and flavor composition--ie, the …

High-energy gamma-ray and neutrino production in star-forming galaxies across cosmic time: Difficulties in explaining the IceCube data

T Sudoh, T Totani, N Kawanaka - Publications of the …, 2018 - academic.oup.com
We present new theoretical modeling to predict the luminosity and spectrum of gamma-ray

IceCube can constrain the intrinsic charm of the proton

R Laha, SJ Brodsky - Physical Review D, 2017 - APS
The discovery of extraterrestrial neutrinos in the∼ 30 TeV–PeV energy range by IceCube
provides new constraints on high energy astrophysics. An important background to the …

First Search for High-Energy Neutrino Emission from Galaxy Mergers

S Bouri, P Parashari, M Das, R Laha - arXiv preprint arXiv:2404.06539, 2024 - arxiv.org
The exact sources of high-energy neutrinos detected by the IceCube neutrino observatory
still remain a mystery. For the first time, this work explores the hypothesis that galaxy …

One-point fluctuation analysis of the high-energy neutrino sky

MR Feyereisen, I Tamborra… - Journal of Cosmology and …, 2017 - iopscience.iop.org
We perform the first one-point fluctuation analysis of the high-energy neutrino sky. This
method reveals itself to be especially suited to contemporary neutrino data, as it allows to …

Hadronuclear interactions in AGN jets as the origin of the diffuse high-energy neutrino background

R Xue, ZR Wang, JC Joshi, WJ Li - arXiv preprint arXiv:2407.04195, 2024 - arxiv.org
The origin of diffuse high-energy neutrinos from TeV to PeV energies detected by IceCube
