Astronomers have found a vast loop-like structure, 20 light years across, adjacent to the most massive star-forming region known in our galaxy. The loop, which was observed in X-ray wavelengths, is 15 ...

The most energetic "ghost particle" neutrino ever detected may have been blasted at Earth by blazars, black hole engines that ...

If this technology becomes reliable, it could move powerful light sources out of a few giant facilities and into ordinary research settings. The team said compact accelerators and x-ray free-electron ...

A gigantic "blazar" may have fired a beam of light-speed particles at our planet, creating a 2023 "ghost particle" detection.

Physicists at multiple institutions are compressing particle accelerators from facility-scale machines stretching hundreds of meters down to devices that fit on a laboratory bench or even a silicon ...

Proof-of-concept experimental setup used to generate an extreme ultraviolet (XUV) free-electron laser (FEL) driven by a laser wakefield acceleration (LWFA) electron beam. An intense laser pulse, ...

A particle detected in 2023 at the bottom of the Mediterranean Sea may have originated from a cosmic particle accelerator ...
