Collaboration makes crystal-clear study of radiation reaction

Place a charged particle in an electromagnetic field and the particle will accelerate and give off radiation. Typically, the emitted radiation has little effect on the particle's motion. However, if the acceleration is extremely ...

How to have a blast like a black hole

Researchers from the Institute of Laser Engineering at Osaka University have successfully used short, but extremely powerful laser blasts to generate magnetic field reconnection inside a plasma. This work may lead to a more ...

Chasing particles with tiny electric charges

All known elementary particles have electric charges that are integer multiples of a third of the electron charge. But some theories predict the existence of "millicharged" elementary particles that would have a charge much ...

Study finds electrical fields can throw a curveball

MIT researchers have discovered a phenomenon that could be harnessed to control the movement of tiny particles floating in suspension. This approach, which requires simply applying an external electric field, may ultimately ...

MoEDAL hunts for dyons

A magnetic monopole is a theoretical particle with a magnetic charge. Give it an electric charge, and you get another theoretical beast, dubbed a dyon. Many "grand unified theories" of particle physics, which connect fundamental ...

Blazar variability

Active galactic nuclei (AGN) are supermassive black holes at the centers of galaxies that are accreting material. These AGN emit jets of charged particles that move at speeds close to that of light, transporting huge amounts ...
