A predictive analytic model for the solar modulation of cosmic rays [PDF]

open access: yes, 2015
An important factor limiting our ability to understand the production and propagation of cosmic rays pertains to the effects of heliospheric forces, commonly known as solar modulation.

The origin of cosmic rays [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 1999
It is generally regarded that the bulk of cosmic rays originate in the Galaxy and that those below the 'knee' (the rapid steepening in the energy spectrum) at a few PeV come from Galactic supernovae, the particles being accelerated by the shocks in the supernova remnants.

Atmospheric effects of stellar cosmic rays on Earth-like exoplanets orbiting M-dwarfs [PDF]

open access: yes, 2015
M-dwarf stars are generally considered favourable for rocky planet detection. However, such planets may be subject to extreme conditions due to possible high stellar activity.

High energy cosmic rays

open access: yesScholarpedia, 2016
New observations with ESO’s Very Large Telescope (VLT) in Chile have revealed alignments over the largest structures ever discovered in the Universe. A European research team has found that the rotation axes of the central supermassive black holes in a ...

Energy estimation of cosmic rays with the Engineering Radio Array of the Pierre Auger Observatory [PDF]

open access: yes, 2015
The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared to the data of the surface detector stations of the Observatory, which ...

Emission of cosmic rays from Jupiter: magnetospheres as possible sources of cosmic rays

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
Measurements made recently with the PAMELA satellite during a period of 8 years have shown with good evidence that a fraction of the cosmic rays detected on Earth comes from Jupiter.

Galactic Cosmic Rays: The first detection of TeV gamma-rays from Red Dwarfs [PDF]

open access: yesEPJ Web of Conferences, 2019
The present point of view on the sources of cosmic rays in Galaxy considers explosions of supernovae as sources of these particles up to energies of 1017 eV.

The Origin of the Cosmic Rays [PDF]

open access: yesPhysical Review, 1928
Maximum energy released by atomic-disintegration (radioactivity.)—From Einstein's equation Mc2=E and Aston's curve the maximum possible energy that can be released in radioactive changes can be computed. The theoretical and experimental values are in satisfactory agreement. Energy released in step-by-step atom-building.—No step-by-step atom-building

Effects of Magnetic Boundary Layer on Galactic Cosmic Rays during the Heliopause Crossing for Voyager 2

open access: yesThe Astrophysical Journal
Voyager 2 crossed the heliopause in 2018 and observed a small-amplitude modulation of galactic cosmic rays beyond the heliopause, within a boundary layer approximately 0.57 au thick. Prior to this, it detected a similar boundary layer for both the cosmic

COSMIC RAYS IN GALAXY CLUSTERS AND THEIR NONTHERMAL EMISSION [PDF]

open access: yes, 2014
Radio observations prove the existence of relativistic particles and magnetic field associated with the intra-cluster-medium (ICM) through the presence of extended synchrotron emission in the form of radio halos and peripheral relics.
