Sporadic acceleration of cosmic rays

open access: yes, 1986
The spectra of primary and secondary cosmic rays generated by the Fermi-acceleration process is derived analytically, exact to all orders. The observed L/M ratios in galactic cosmic rays constrain the frequency of encounters and the amount of ...

Detection of primary photons in high energy cosmic rays using Cherenkov imaging and surface detectors

open access: yes, 2017
Discovered by Hess during some experiments about air ionization, cosmic rays are constituted by particles coming from the space. In the past, cosmic rays allowed the development of Particle Physics; indeed, thanks to their high energy not achievable in ...

The effect of secondary cosmic rays on spontaneous mutability

open access: yesBiologia Plantarum, 1967
V ramci SirSiho studia problematiky spontanni mutability a ucinků kosmickuho zařeni bylo nutno vyjit z fysikalniho hlediska z nulových hodnot. Těch bylo prakticky dosaženo v hloubce 1340 m pod zemi SporyEquisetum arvense, E. silvaticum aE. palustre na tomto stanoviSti a na povrchu země (250 m n. m.) byly testovany na výskyt abnormalniho děleni plastidů

Antiprotons in primary cosmic radiation with PAMELA experiment

open access: yes, 2013
The latest measurements of antiprotons spectrum and antiproton-to-proton ratio in primary cosmic rays with PAMELA experiment are presented. They are in good agreement with model of secondary production of antiprotons in Galaxy, but they do not completely

Secondary gamma rays from ultrahigh energy cosmic rays produced in magnetized environments

open access: yes, 2006
Nearby sources of cosmic rays up to a ZeV(=$10^21 eV) could be observed with a multimessenger approach including secondary gamma-rays and neutrinos. If cosmic rays above ~$10^18$ eV are produced in magnetized environments such as galaxy clusters, the ...

Cosmogenic Origin of KM3-230213A: Delayed Gamma-Ray Emission from a Cosmic-Ray Transient

open access: yesThe Astrophysical Journal Letters
The highest-energy cosmic neutrino detected by the ARCA detector of KM3NeT has reignited the quest to pinpoint the sources of ultrahigh-energy cosmic rays (UHECRs; E  ≳ 0.1 EeV).
