EPJ Web of Conferences, 2015 The multi-facet nature of the origin of cosmic rays is such that some of the problems currently met in our path to describing available data are due to oversimplified models of CR acceleration and transport, and others to lack of knowledge of the ...

Diffuse Emission of Galactic High-energy Neutrinos from a Global Fit of Cosmic Rays [PDF]
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.

First Detection of sub-PeV Diffuse Gamma Rays from the Galactic Disk: Evidence for Ubiquitous Galactic Cosmic Rays beyond PeV Energies [PDF]
Physical Review Letters, 2021 We report, for the first time, the long-awaited detection of diffuse gamma rays with energies between 100 TeV and 1 PeV in the Galactic disk. Particularly, all gamma rays above 398 TeV are observed apart from known TeV gamma-ray sources and compatible ...

Closing in on the origin of Galactic cosmic rays using multimessenger information [PDF]
Physics Reports, 2020 In cosmic ray physics extensive progress has been made in recent years, both concerning theory and observation. The vast details in direct, indirect and secondary detections on the one hand provide the basis for a detailed modeling of the signatures via ...

Central Nervous System Responses to Simulated Galactic Cosmic Rays. [PDF]
Int J Mol Sci, 2018 In preparation for lunar and Mars missions it is essential to consider the challenges to human health that are posed by long-duration deep space habitation via multiple stressors, including ionizing radiation, gravitational changes during flight and in ...

Cooler and smoother – the impact of cosmic rays on the phase structure of galactic outflows [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We investigate the impact of cosmic rays (CRs) on galactic outflows from a multi-phase interstellar medium with solar neighbourhood conditions. The three-dimensional magneto-hydrodynamical simulations include CRs as a relativistic fluid in the advection ...

Massive stars as major factories of Galactic cosmic rays
Nature Astronomy, 2019 The identification of the main contributors to the locally observed fluxes of cosmic rays is a prime objective in the resolution of the long-standing enigma of the source of cosmic rays.
