LHAASO has uncovered that micro-quasars, black holes feeding on companion stars, are powerful PeV particle accelerators. Their jets produce ultra-high-energy gamma rays and protons that exceed ...

Every time two beams of particles collide inside an accelerator, the universe lets us in on a little secret. Sometimes it's a particle no one has ever seen. Other times, it's a fleeting glimpse of ...

Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists ...

Traditional particle accelerators, including radiofrequency linear accelerators and synchrotrons, have pushed physics forward for decades. They are also expensive, physically large, and limited in how ...

Alex Bogacz, a senior scientist at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility since 1997, has spent his career in accelerator physics solving problems. From ...

Scientists have detected the highest-energy "ghost particle" ever seen. The particle, a type of neutrino, arrived at Earth at nearly the speed of light and with 30 times the energy of the previous ...
