TL;DR: In this article, the authors proposed a scenario in which the thermal electrons in the hot plasma responsible for the strong Fe K X-ray emission are shock-accelerated continuously in supernova remnants (SNRs), producing the observed hard Xray and γ-ray emissions from the Galactic ridge.

X-Ray Observations of Stellar Clusters Near the Galactic Center
Casey J. Law,Farhad Yusef-Zadeh +1 more
TL;DR: In this paper, the first detection of X-ray emission from the Quintuplet star cluster was reported and compared to that of the Arches star cluster, and the authors analyzed the diffuse and point-like emission from both Arches and Q star clusters and discussed the possibility that they are host to wind outflows.

Origin of small-scale anisotropies in Galactic cosmic rays
Markus Ahlers,Philipp Mertsch +1 more
TL;DR: In this article, the authors summarize the current experimental situation for both the large-scale and small-scale anisotropies, and address some of the issues in comparing different experimental results and remaining questions in interpreting the observed large scale anisotropic properties.

Cosmic Ray Origins: An Introduction
TL;DR: In this paper, a review of the basic features of the entire cosmic ray spectrum from GeV to ZeV energy and some of the models that have been developed is presented. And a connection is made to recent developments in understanding general astrophysical particle acceleration in pulsar wind nebulae, relativistic jets and gamma ray bursts.

Wakefield Acceleration by Radiation Pressure in Relativistic Shock Waves
TL;DR: In this article, a particle acceleration mechanism by radiation pressure of precursor waves in a relativistic, perpendicular shock was studied, and it was shown that nonthermal, high-energy electrons and ions can be quickly produced by an action of electrostatic wakefields generated by the ponderomotive force of the precursor waves.
