Modulation of Galactic Cosmic Rays in the Inner Heliosphere, Comparing with PAMELA Measurements [PDF]
, 2017 We develop a numerical model to study the time-dependent modulation of galactic cosmic rays in the inner heliosphere. In the model, a time-delayed modified Parker heliospheric magnetic field (HMF) and a new diffusion coefficient model, NLGCE-F, from Qin &

Cosmic Ray Processes in Galactic Ecosystems
Galaxies, 2023 Galaxy evolution is an important topic, and our physical understanding must be complete to establish a correct picture. This includes a thorough treatment of feedback. The effects of thermal–mechanical and radiative feedback have been widely considered; however, cosmic rays (CRs) are also powerful energy carriers in galactic ecosystems.

Cosmic rays in early star-forming galaxies and their effects on the interstellar medium [PDF]
, 2017 Galaxies at high redshifts with strong star formation are sources of high-energy cosmic rays. These cosmic rays interact with the baryon and radiation fields of the galactic environment via photo-pair, photo-pion and proton-proton processes to produce ...

Evidence for a Time Lag in Solar Modulation of Galactic Cosmic Rays [PDF]
, 2017 The solar modulation effect of cosmic rays in the heliosphere is an energy-, time-, and particle-dependent phenomenon that arises from a combination of basic particle transport processes such as diffusion, convection, adiabatic cooling, and drift motion.

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
