Cosmic-Ray Boosted Diffuse Supernova Neutrinos
AstronomyThe subject of boosted fluxes of dark matter or cosmic relic neutrinos via scattering on cosmic rays has received considerable attention recently. This article investigates the boosted neutrino flux from the scattering of cosmic rays and the so-far ...

The mass composition of cosmic rays measured with LOFAR
EPJ Web of Conferences, 2017 High-energy cosmic rays, impinging on the atmosphere of the Earth initiate cascades of secondary particles, the extensive air showers. The electrons and positrons in the air shower emit electromagnetic radiation.

Possible Counterpart Signal of the Fermi Bubbles at the Cosmic-Ray Positrons
The Astrophysical Journal, 2023 The inner Galaxy has hosted cosmic-ray burst events, including those responsible for the gamma-ray Fermi bubbles and the eROSITA bubbles in X-rays. In this work, we study the Alpha Magnetic Spectrometer positron fraction and find three features around 12,

Galactic cosmic ray modulation near the heliospheric current sheet
, 2014 Galactic cosmic rays (GCRs) are modulated by the heliospheric magnetic field (HMF) both over decadal time scales (due to long-term, global HMF variations), and over time scales of a few hours (associated with solar wind structures such as coronal mass ...

Galactic cosmic rays on extrasolar Earth-like planets - II. Atmospheric implications [PDF]
, 2016 Context. Theoretical arguments indicate that close-in terrestial exoplanets may have weak magnetic fields, especially in the case of planets more massive than Earth (super-Earths).

On the radial distribution of Galactic cosmic rays [PDF]
, 2016 The spectrum and morphology of the diffuse Galactic gamma-ray emission carries valuable information on cosmic ray (CR) propagation. Recent results obtained by analyzing Fermi-LAT data accumulated over seven years of observation show a substantial ...

Cosmic ray-driven winds in the Galactic environment and the cosmic ray spectrum [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 Cosmic Rays escaping the Galaxy exert a force on the interstellar medium directed away from the Galactic disk. If this force is larger than the gravitational pull due to the mass embedded in the Galaxy, then galactic winds may be launched. Such outflows may have important implications for the history of star formation of the host galaxy, and in turn ...

Sagittarius A* as an origin of the Galactic PeV cosmic rays? [PDF]
, 2016 Supernova remnants (SNRs) have commonly been considered as a source of the observed PeV cosmic rays (CRs) or a Galactic PeV particle accelerator ("Pevatron").
