High-energy cosmic ray production in X-ray binary jets
@article{Cooper2020HighenergyCR, title={High-energy cosmic ray production in X-ray binary jets}, author={A J Cooper and Daniele Gaggero and Sera B. Markoff and S. Zhang}, journal={Monthly Notices of the Royal Astronomical Society}, year={2020} }
As smaller analogues of active galactic nuclei, X-ray binaries (XRBs) are also capable of launching jets that accelerate particles to high energies. In this work, we re-examine XRB jets as potential sources of high-energy cosmic rays (CRs) and explore whether they could provide a significant second Galactic component to the CR spectrum. In the most intriguing scenario, XRB-CRs could dominate the observed spectrum above the so-called knee feature at ∼3 × 1015 eV, offering an explanation for…

These observations reveal evidence for a hot continuum and Doppler-shifted iron emission lines from spatially resolved regions and in situ reheating of the baryonic component of the jets takes place in a flow that moves with relativistic bulk velocity even more than 100 days after launch from the binary core.

Extreme particle acceleration in the microquasar Cygnus X-3
- PhysicsNature

There is a clear pattern of temporal correlations between the γ-ray flares and transitional spectral states of the radio-frequency and X-ray emission, and particle acceleration occurred a few days before radio-jet ejections for two of the four flares, meaning that the process of jet formation implies the production of very energetic particles.

Radio measurements of Xmax with a mean uncertainty of 16 grams per square centimetre for air showers initiated by cosmic rays with energies of 1017–1017.5 electronvolts enable us to determine the mass spectrum of the cosmic rays: a mixed composition, with a light-mass fraction (protons and helium nuclei) of about 80 per cent.
