Scientists have come a step closer to understanding how collisionless shock waves—found throughout the universe—are able to accelerate particles to extreme speeds. The research, published in Nature ...

For the past 30 years, an acceleration mechanism — diffusive shock acceleration (DSA) 3 — has been developed to explain this acceleration. A key aspect of DSA is the prediction that it is highly ...

Composite image of the Tycho Supernova remnant. Shock waves from such explosive events are believed to be the main drivers behind cosmic rays. Scientists have come a step closer to understanding how ...

Researchers from the University of Science and Technology of China (USTC) achieved the first direct laboratory observation of ion acceleration through reflection off laser-generated magnetized ...

RX J1713.7-3946 (ref. 5) is a unique remnant of a supernova in the sense that its X-ray emission is strongly dominated by a non-thermal component 6,7,8,9, which has been presumed to be synchrotron ...

In space, supernova explosions, black holes, and other cosmic events can accelerate particles (like electrons) to incredibly high speeds, even rivaling the velocity of light. This is termed ...

Understanding how particles such as electrons travel vast distances in space or how they acquire ultra-high energy has been a long-standing puzzle in astrophysics. In fact, physicists’ picture of the ...
