Heliospheric modulation of cosmic rays during the neutron monitor era: Calibration using PAMELA data for 2006–2010 [PDF]
, 2017 A new reconstruction of the heliospheric modulation potential for galactic cosmic rays is presented for the neutron monitor era, since 1951. The new reconstruction is based on an updated methodology in comparison to previous reconstructions: (1) the use ...

Ultra-high-energy cosmic rays and neutrinos from tidal disruptions by massive black holes [PDF]
Astronomy & Astrophysics, 2017 Tidal disruptions are extremely powerful phenomena that have been designated as candidate sources of ultra-high-energy cosmic rays. The disruption of a star by a black hole can naturally provide protons and heavier nuclei, which can be injected and ...

A precision search for WIMPs with charged cosmic rays [PDF]
, 2017 AMS-02 has reached the sensitivity to probe canonical thermal WIMPs by their annihilation into antiprotons. Due to the high precision of the data, uncertainties in the astrophysical background have become the most limiting factor for indirect dark matter

Testing hadronic and photo-hadronic interactions as responsible for UHECR and neutrino fluxes from Starburst Galaxies [PDF]
EPJ Web of Conferences, 2023 We test the hypothesis that starburst galaxies are the sources of ultra-high energy cosmic rays and high-energy neutrinos. The computation of interactions of ultra-high energy cosmic rays in the starburst environment as well as in the propagation to the ...

On the Search for the Galactic PeVatrons by Means of Gamma-Ray Astronomy
Universe, 2022 Cosmic rays are ultra-relativistic particles that slam into the atmosphere from all directions in the sky. Gamma rays emitted when cosmic rays interact with Galactic gas and radiation fields are a powerful tool to investigate their origin. Many candidate

Active Galactic Nuclei with Starbursts: Sources for Ultra High Energy Cosmic Rays [PDF]
, 2009 Ultra high energy cosmic ray events presently show a spectrum, which we interpret here as galactic cosmic rays due to a starburst in the radio galaxy Cen A pushed up in energy by the shock of a relativistic jet.

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 ...
