High-Energy Extragalactic Neutrino Astrophysics [PDF]

open access: greenAnnual Review of Nuclear and Particle Science, 2022
The detection of an astrophysical flux of neutrinos in the TeV–PeV energy range by the IceCube Neutrino Observatory has opened new possibilities for the study of extreme cosmic accelerators. The apparent isotropy of the neutrino arrival directions favors

TESTING LORENTZ SYMMETRY USING HIGH ENERGY ASTROPHYSICS OBSERVATIONS. [PDF]

open access: yesSymmetry (Basel), 2017
We discuss some of the tests of Lorentz symmetry made possible by astrophysical observations of ultrahigh energy cosmic rays, γ-rays, and neutrinos. These are among the most sensitive tests of Lorentz invariance violation because they are the highest ...

A radiation transfer model for the Milky Way: I. Radiation fields and application to high-energy astrophysics★ [PDF]

open access: green, 2017
We present a solution for the ultraviolet (UV) - submillimeter (submm) interstellar radiation fields (ISRFs) of the Milky Way, derived from modelling COBE, IRAS and Planck maps of the all-sky emission in the near-, mid-, far-infrared and submm.

HARPO - TPC for High Energy Astrophysics and Polarimetry from the MeV to the TeV [PDF]

open access: hybrid, 2015
Observation of high-energy sources requires gamma-ray telescopes aboard balloons or satellites to study non thermal phenomena (black holes, neutron stars, active galactic nuclei, supernovae, supernova remnants, and gamma-ray bursts). In recent years, R&D

Magnetic Reconnection and Associated Particle Acceleration in High-Energy Astrophysics [PDF]

open access: yesSpace Science Reviews, 2023
Magnetic reconnection occurs ubiquitously in the universe and is often invoked to explain fast energy release and particle acceleration in high-energy astrophysics.

Axion-like Particles Implications for High-Energy Astrophysics [PDF]

open access: yesUniverse, 2022
We offer a pedagogical introduction to axion-like particles (ALPs) as far as their relevance for high-energy sstrophysics is concerned, from a few MeV to 1000 TeV. This review is self-contained, in such a way to be understandable even to non-specialists.

Panoramic SETI: program update and high-energy astrophysics applications [PDF]

open access: yesAstronomical Telescopes + Instrumentation, 2022
Optical SETI (Search for Extraterrestrial Intelligence) instruments that can explore the very fast time domain, especially with large sky coverage, offer an opportunity for new discoveries that can complement multimessenger and time domain astrophysics ...

LeHaMoC: A versatile time-dependent lepto-hadronic modeling code for high-energy astrophysical sources [PDF]

open access: yesAstronomy & Astrophysics, 2023
Recent associations of high-energy neutrinos with active galactic nuclei (AGN) have revived the interest in leptohadronic models of radiation from astrophysical sources.

Flavor anisotropy in the high-energy astrophysical neutrino sky [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2023
High-energy astrophysical neutrinos, with TeV–PeV energies, offer unique insight into astrophysics and particle physics. Their incoming directions and flavor composition — i.e., the proportion of νe , νμ , and ντ in their flux — are, individually ...

CRPropa 3.2 — an advanced framework for high-energy particle propagation in extragalactic and galactic spaces [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2022
The landscape of high- and ultra-high-energy astrophysics has changed in the last decade, largely due to the inflow of data collected by large-scale cosmic-ray, gamma-ray, and neutrino observatories.
