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 ...

How to use molecular clouds to study the propagation of cosmic rays in the Galaxy [PDF]
, 2010 Observations of molecular clouds in the gamma ray domain provide us with a tool to study the distribution of cosmic rays in the Galaxy. This is because cosmic rays can penetrate molecular clouds, undergo hadronic interactions in the dense gas, and produce neutral pions that in turn decay into gamma rays.

Connecting blazars with ultrahigh-energy cosmic rays and astrophysical neutrinos [PDF]
, 2016 We present a strong hint of a connection between high energy $\gamma$-ray emitting blazars, very high energy neutrinos, and ultra high energy cosmic rays.

Testing Fundamental Physics with High-Energy Cosmic Rays [PDF]
Nuovo Cim.C24:483-496,2001, 2000 Cosmic rays may provide opportunities for probing fundamental physics. For example, ultra-high-energy cosmic rays might originate from the decays of metastable heavy particles, and astrophysical gamma rays can be used to test models of quantum gravity. Both scenarios offer ways to avoid the GZK cut-off.

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

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
