Continuous solutions of cosmic-rays and waves in astrophysical environments [PDF]
Scientific Reports, 2023 The propagation of energetic charged particles and cosmic rays in magnetized thermal plasma is focused. We consider a four-fluid system that consists of thermal plasma, cosmic rays, and two opposite propagating Alfvén waves to investigate the dynamics ...

Physics Letters B, 2017 If dark matter particles have an electric charge, as in models of millicharged dark matter, such particles should be accelerated in the same astrophysical accelerators that produce ordinary cosmic rays, and their spectra should have a predictable ...

HAWC observations of the acceleration of very-high-energy cosmic rays in the Cygnus Cocoon [PDF]
Nature Astronomy, 2021 Cosmic rays with energies up to a few PeV are known to be accelerated within the Milky Way1,2. Traditionally, it has been presumed that supernova remnants were the main source of these very-high-energy cosmic rays3,4, but theoretically it is difficult to

Properties of Iron Primary Cosmic Rays: Results from the Alpha Magnetic Spectrometer.
Physical Review Letters, 2021 We report the observation of new properties of primary iron (Fe) cosmic rays in the rigidity range 2.65 GV to 3.0 TV with 0.62×10^{6} iron nuclei collected by the Alpha Magnetic Spectrometer experiment on the International Space Station.

Examination of Xmax anisotropy for the next generation Ultra-high energy cosmic rays observations [PDF]
EPJ Web of Conferences, 2023 The estimation of mass composition ultra-high energy cosmic rays is essential to understand their origin and generation mechanism. Recent experiments are expected to discover anisotropy of mass composition in ultra-high energy cosmic rays.

Impact of Low-Energy Cosmic Rays on Star Formation [PDF]
, 2020 In recent years, exciting developments have taken place in the identification of the role of cosmic rays in star-forming environments. Observations from radio to infrared wavelengths and theoretical modelling have shown that low-energy cosmic rays ( < 1

Texture-based brain networks for characterization of healthy subjects from MRI
Scientific Reports, 2023 Brain networks have been widely used to study the relationships between brain regions based on their dynamics using, e.g. fMRI or EEG, and to characterize their real physical connections using DTI.
