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

Microquasar V4641 Sgr and Its Deep Investigation with LACT as a Super-PeVatron of Cosmic Rays [PDF]
ResearchSeveral instruments, including LHAASO, have measured γ-ray emission from the direction of V4641 Sgr, a well known microquasar. The emission measured with LHAASO is best described as a power-law spectrum extending into the ultra-high-energy regime with no

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

High-Energy Extragalactic Neutrino Astrophysics [PDF]
Annual 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
