The mass composition of cosmic rays with the highest energies is determined from the fraction of muons within the framework of the QGSJetII-04. Introduction The impulse for the study of the properties of cosmic rays was undoubtedly the discovery of cosmic radiation by W. Hess in 1912 (Hess,...

High-resolution radio measurements of air showers—cascades of secondary particles in the atmosphere initiated by cosmic rays—reveal that cosmic rays with energies of 1017–1017.5 electronvolts have a mixed composition, with light elements (protons and
in Beijing, capital of China, Feb. 22, 2024. China's cosmic ray observatory has discovered a giant ultra-high-energy gamma-ray bubble structure, about ten million times larger than our solar system, in the Cygnus star-forming region, around 5,000 light years from Earth.(Xinhua/Jin Liwang...
Pulsar, any of a class of cosmic objects, the first of which were discovered through their extremely regular pulses of radio waves. Some objects are known to give off short rhythmic bursts of visible light, X-rays, and gamma radiation as well, and others

(see Supplementary Fig.1). They all stopped on March 13th 2020 after an electricity cut due to a storm. Charpak was restarted on March 18th at a reduced gas flow, and definitely stopped on April 6th following the COVID-19 pandemic. All in all, Degennes and Joliot accumulated about 140...
Gamma-ray bursts (GRBs) are short-lived, luminous explosions at cosmological distances, thought to originate from relativistic jets launched at the deaths of massive stars. They are among the prime candidates to produce the observed cosmic rays at the highest energies. Recent neutrino data have, ...
