Black hole jets are known to emit x-rays, but how they accelerate particles to this high-energy state is still a mystery. Surprising new findings appear to rule out a leading theory, opening the door ...

In high-intensity laser–matter interactions, including laser-induced particle acceleration, physicists generally want to work ...

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 ...

For scientists studying the impacts of space weather, one of the central mysteries of solar flares. Solar flares are the colossal release of magnetic energy in the Sun’s atmosphere that erupts with ...

Researchers from Trinity College Dublin's School of Engineering have built a powerful new machine that lets us watch precisely what happens when tiny particles—far smaller than a grain of sand—hit a ...
