Microquasars—compact regions surrounding a black hole with a mass several times that of its companion star—have long been recognized as powerful particle accelerators within our galaxy. The enormous jets spewing out of microquasars are thought to play an important role in the production of galactic cosmic rays, although [...]

Where do the highest-energy particles in the universe come from? New research led by WIPAC researchers suggests that the sources of ultra-high-energy cosmic rays aren’t necessarily the sources of ultra-high-energy photons as well. Cosmic Rays Across the Universe Across the universe, extremely energetic charged particles called cosmic [...]
