Context. Various signals of anisotropy of the ultra-high-energy cosmic rays (UHECRs) have
recently been reported, whether at large angular scales, with a dipole modulation in right …

Ultra-high energy cosmic rays are the most extreme energetic particles detected on Earth,
however, their acceleration sites are still mysterious. We explore the contribution of low …

The cosmic-ray spectrum structures help to study the acceleration and propagation
mechanism of ultra-high energy cosmic rays, and these structures were predicted to …

In this study, authors investigate a novel framework incorporating exponential
electrodynamics and d-dimensional energy-dependent massive gravity. Our focus lies in …

We report on an observation of the difference between northern and southern skies of the
ultrahigh energy cosmic ray energy spectrum with a significance of ${\sim} 8\sigma $. We …

Cosmic rays are a very valuable tool of multi‐messenger astrophysics, as they provide a
very different picture of the sky. During the past decades, a large number of active …

This chapter presents the study and temporal and spectral characterization of the MWL
emission from the blazar 1ES0647+ 250. A work I have contributed to as one of the main …

CORSIKA is a detailed simulation program for extensive air showers initiated by high energy
cosmic particles. The user's guide explains the installation of the code, all the necessary …

We begin this chapter with a brief historical account of the early papers that discuss these
ultra-high-energy (UHE) neutrinos. Then we introduce all processes and photon targets that …
