We review some of the recent progress in our knowledge about high-energy cosmic rays,
with an emphasis on the interpretation of the different observational results. We discuss the …

Abstract The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to
accurately observe ultra-high-energy cosmic rays (UHECRs) and cosmic neutrinos from …

The “Lomonosov” space project is lead by Lomonosov Moscow State University in
collaboration with the following key partners: Joint Institute for Nuclear Research, Russia …

The sources of ultrahigh-energy cosmic rays (UHECRs) have been stubbornly elusive.
However, the latest report of the Pierre Auger Observatory provides a compelling indication …

Ultra-High-Energy Cosmic-Ray (UHECR) astronomy in the next decade aims to answer the
questions: What is the nature and origin of UHECRs? How are UHECRs accelerated to such …

The origin of the ultra high energy cosmic rays (UHECRs, E> 10 18 eV) is still uncertain.
However, great progress has been achieved due to the data taken by The Pierre Auger and …

The sources of ultrahigh-energy cosmic rays (UHECRs) have been difficult to catch. It was
recently pointed out that while sources of UHECR protons exhibit anisotropy patterns that …

We argue that if ultrahigh-energy (E≳ 10 10 GeV) cosmic rays are heavy nuclei (as indicated
by existing data), then the pointing of cosmic rays to their nearest extragalactic sources is …

The quest for the origin (s) of ultra-high-energy cosmic rays (UHECRs) continues to be a far-
reaching pillar of high energy astrophysics. The source scrutiny is mostly based on three …

Our planet is constantly hit by a stream of energetic subatomic particles, which are known as
'cosmic rays'. These particles are mostly protons, but also heavier nuclei, as well as small …
