The Auger@TA Project: Phase II Progress and Plans [PDF]
EPJ Web of Conferences, 2019 The Auger@TA project is a combined effort involving members of both the Pierre Auger Observatory and the Telescope Array experiment (TA) to cross-calibrate detectors and compare results on air showers detected at one location.

Unparticle effects on cosmic ray photon and $e^\pm$ [PDF]
, 2009 We study the effects of unparticle physics on the cosmic ray photon and $e^\pm$, including on the pair production (PP) and elastic scattering (ES) of cosmic ray photon off various background radiations, and on the inverse Compton scattering of cosmic ray

Cosmic ray feedback in the FIRE simulations: constraining cosmic ray propagation with GeV γ-ray emission [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We present the implementation and the first results of cosmic ray (CR) feedback in the Feedback In Realistic Environments (FIRE) simulations. We investigate CR feedback in non-cosmological simulations of dwarf, sub-L⋆ starburst, and L⋆ galaxies with ...

New Universal Cosmic-Ray Knee near a Magnetic Rigidity of 10 TV with the NUCLEON Space Observatory [PDF]
JETP Letters : Journal of Experimental And Theoretical Physics Letters, 2018 Data from the NUCLEON space observatory give a strong indication of the existence of a new universal cosmic ray “knee”, which is observed in all groups of nuclei, including heavy nuclei, near a magnetic rigidity of about 10 TV.

Cosmic rays and space weather: effects on global climate change [PDF]
Annales Geophysicae, 2012 We consider possible effects of cosmic rays and some other space factors on the Earth's climate change. It is well known that the system of internal and external factors formatting the climate is very unstable; decreasing planetary temperature leads ...

Measurements of the isotopes of lithium, beryllium, and boron from ACE/CRIS [PDF]
, 2001 The isotopes of lithium, beryllium, and boron (LiBeB) are known in nature to be produced primarily by CNO spallation and α-α fusion from interactions between cosmic rays and interstellar nuclei.

Origin of the Cosmic Ray Galactic Halo Driven by Advected Turbulence and Self-Generated Waves. [PDF]
Physical Review Letters, 2018 The diffusive paradigm for the transport of Galactic cosmic rays is central to our understanding of the origin of these high energy particles. However, it is worth recalling that the normalization, energy dependence, and spatial extent of the diffusion ...

Radiation Exposure in the Lower Atmosphere during Different Periods of Solar Activity
Atmosphere, 2022 In recent years, there has been a huge increase in air travel, both for business and leisure. For this reason, entities such as the European Commission and the International Committee on Radiological Protection have provided several recommendations for ...

Cosmic-ray hydrodynamics: Alfvén-wave regulated transport of cosmic rays [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Star formation in galaxies appears to be self-regulated by energetic feedback processes. Among the most promising agents of feedback are cosmic rays (CRs), the relativistic ion population of interstellar and intergalactic plasmas.
