Search for Joint Multimessenger Signals from Potential Galactic Cosmic-Ray Accelerators with HAWC and IceCube

open access: yesThe Astrophysical Journal
The origin of high-energy galactic cosmic rays is yet to be understood, but some galactic cosmic-ray accelerators can accelerate cosmic rays up to PeV energies.

SAS-2 observations of the galactic gamma radiation from the Vela region [PDF]

open access: yes
Data from a scan of the galactic plane by the SAS-2 high energy gamma ray experiment in the region 250 deg l2 290 deg show a statistically-significant excess over the general radiation from the galactic plane for gamma radiation of energy 100 MeV in ...

Rigidity Dependence of the Long-term Galactic Cosmic Ray Variation by AMS-02

open access: yesThe Astrophysical Journal
Using measurements from the Alpha Magnetic Spectrometer (AMS-02) aboard the International Space Station, we have examined the long-term variations in galactic cosmic ray (GCR) proton fluxes in 2011–2018.

SAS-2 observations of the high energy gamma radiation from the Vela region [PDF]

open access: yes
Data from a scan of the galactic plane by the SAS-B high energy gamma ray experiment in the region 250 deg smaller than 12 smaller than 290 deg show a statistically significant excess over the general radiation from the galactic plane for gamma radiation

Testing Cosmic-Ray Propagation Scenarios with AMS-02 and Voyager Data

open access: yesThe Astrophysical Journal
AMS-02 on board the International Space Station provides precise measurements of cosmic rays (CR) near Earth, while Voyager measures CRs in the local interstellar medium, beyond the effects of solar modulation.

Cosmogenic nuclei [PDF]

open access: yes
Cosmogenic nuclei, nuclides formed by nuclear interactions of galactic and solar cosmic rays with extraterrestrial or terrestrial matter are discussed. Long lived radioactive cosmogenic isotopes are focused upon.
