Inverse Compton emission from a cosmic-ray precursor in RX J1713.7−3946
Yutaka Ohira,Ryo Yamazaki +1 more
TL;DR: In this article, the authors show that if the maximum energy of electrons being accelerated decreases with time, the broken power-law spectrum can be generated by accumulation, and the extended component of γ-ray profile can be interpreted as a CR precursor of currently accelerated electrons.
Journal ArticleDOI
Diffuse Galactic gamma rays from shock-accelerated cosmic rays.
TL;DR: A flux of shock-accelerated cosmic-ray protons with s≈2.8 provides an adequate fit to the Fermi Large Area Telescope γ-ray emission spectra of high-latitude and molecular cloud gas when uncertainties in nuclear production models are considered.

Dynamical ejecta synchrotron emission as a possible contributor to the changing behaviour of GRB170817A afterglow
Vsevolod Nedora,David Radice,Sebastiano Bernuzzi,Albino Perego,Boris Daszuta,Andrea Endrizzi,Aviral Prakash,Federico Schianchi +7 more
TL;DR: In this article, the authors show that the fading non-thermal emission from the GW170817 remained generally consistent with the synchrotron afterglow from the forward shock of a relativistic structured jet.
Journal ArticleDOI
Modeling the shock aftermath source of energetic particles in the solar corona
TL;DR: In this article, a Monte Carlo technique was employed to model the diffusive shock acceleration of protons in a turbulent layer at the base of the solar wind for a few tens of minutes after the CME liftoff.

Particle Acceleration at the Earth's Bow Shock
TL;DR: The Earth's bow shock is a region of large amplitude turbulence, containing coherent structures and wavetrains as discussed by the authors, and it has been shown that energetic particle diffusion, a fundamental assumption of the Fermi process, operates at the bow shock.
