The GRAND project and GRANDProto300 experiment [PDF]

EPJ Web of Conferences, 2019
The Giant Array for Neutrino Detection (GRAND) is a proposal for a giant observatory of ultra-high energy cosmic particles (neutrinos, cosmic rays and gamma rays). It will be composed of twenty subarrays of 10 000 antennas each, totaling a detection area

COSMIC RAY ANTIPROTONS [PDF]

Particles, Strings and Cosmology (PASCOS 99), 2000
Cosmic ray antiprotons have been detected for over 20 years and are now measured reliably. Standard particle and astrophysics predict a conventional spectrum and abundance of secondary antiprotons consistent with all current measurements. These measurements place limits on exotic Galactic antiproton sources and non-standard antiproton properties ...

Simulation Study of Optical Band Radiation during the Afterglow Phase of Gamma-Ray Bursts Based on the HADAR Experiment

The Astrophysical Journal
Studying the afterglow of gamma-ray bursts (GRBs) is essential for refining theoretical models, uncovering their underlying physical processes, and exploring potential new physics. Multiwavelength investigations have emerged as a fundamental approach for

Diffuse Emission of Galactic High-energy Neutrinos from a Global Fit of Cosmic Rays

The Astrophysical Journal, 2023
In the standard picture of Galactic cosmic rays, a diffuse flux of high-energy gamma rays and neutrinos is produced from inelastic collisions of cosmic-ray nuclei with the interstellar gas.

Precision Measurement of the Proton Flux in Primary Cosmic Rays from Rigidity 1 GV to 1.8 TV with the Alpha Magnetic Spectrometer on the International Space Station. [PDF]

Physical Review Letters, 2014
A precise measurement of the proton flux in primary cosmic rays with rigidity (momentum/charge) from 1 GV to 1.8 TV is presented based on 300 million events. Knowledge of the rigidity dependence of the proton flux is important in understanding the origin,

ON THE E/P-COSMIC RAYS AS MEDIATORS OF VISCOUS FORCES THAT CREATE SHOCK AND VORTEX STRUCTURES IN THE RADIO GALAXIES

Odessa Astronomical Publications, 2016
There are for the galaxies of FRII type (like Cygnus A) studied a number of hydrodynamic and kinetic processes to transport of magnetized plasma with cosmic rays, and a stratification process of RG-lobe because of e\p-cosmic rays.

The LHAASO experiment: from Gamma-Ray Astronomy to Cosmic Rays [PDF]

, 2016
LHAASO is expected to be the most sensitive project to face the open problems in Galactic cosmic ray physics through a combined study of photon- and charged particle-induced extensive air showers in the energy range 10$^{11}$ - 10$^{17}$ eV.

COSMIC RAYS AT THE KNEE [PDF]

Energy Budget in the High Energy Universe, 2007
Several kinds of measurements are combined in an attempt to obtain a consistent estimate of the spectrum and composition of the primary cosmic radiation through the knee region. Assuming that the knee is a signal of the high-energy end of a galactic cosmic-ray population, I discuss possible signatures of a transition to an extra-galactic population and

Inferring the Intrinsic Population and Cosmic Rate of Short Gamma-Ray Bursts through Forward Modeling of Fermi/GBM and Swift/BAT Observations

The Astrophysical Journal
Short gamma-ray bursts (sGRBs) are widely believed to originate from mergers of compact binaries, including binary neutron stars and neutron star–black hole systems. However, the observed sGRB population is strongly shaped by selection effects associated
