New research published by Michigan State University astrophysicists could help scientists answer a century-old question: Where did galactic cosmic rays come from? Cosmic rays—high-energy particles ...

Cosmic rays, high-energy particles that travel through space, have puzzled scientists for decades. One particular feature of their energy spectrum—the “knee”—has long remained a mystery. Recent ...

Cosmic ray air showers are produced when high-energy cosmic particles enter Earth’s atmosphere and interact with atmospheric nuclei, generating cascades of secondary particles. These extensive air ...

The findings, published in The Astrophysical Journal, provide fresh insights into ultraluminous X-ray sources (ULXs) — among the brightest and most enigmatic objects known in astrophysics.

The study of cosmic rays, high-energy particles originating from extraterrestrial sources, has significantly progressed with the advent of both ground-based and space-borne detection techniques.

The most energetic particles in the universe – ultrahigh-energy cosmic rays – likely come from supermassive black holes in the hearts of nearby active galaxies, says a study by scientists from nearly ...

An international team of astronomers, led by researchers from the Astronomical Observatory of the University of Warsaw, have identified a new class of cosmic X-ray sources. The findings have been ...

For the first time, an international collaboration of more than 800 scientists has joined forces to track down the sources of high-energy cosmic neutrinos. By combining neutrino observations with ...

The universe is a stage filled with extreme phenomena, where temperatures and energies reach unimaginable levels. In this context, there are objects such as supernova remnants, pulsars, and active ...
