Meanwhile, we have observed something quite incredible in the data recorded by the detectors of the HAWC observatory: photons ...

Astronomers have made a shocking discovery that’s rewriting the way we think about cosmic powerhouses. While scientists ...

Scientists have long thought that the highest-energy gamma rays in space are forged in the intense furnaces of very active ...

For a long time, astronomers believed that extremely high-energy radiation was produced only in the jets of active galaxies, far from Earth. But new observations from the High-Altitude Water Cherenkov ...

Researchers have discovered something groundbreaking in the world of astrophysics—an incredible system where not one, but a ...

An astrophysical object called a microquasar in the Milky Way has been found to emit γ-rays. The discovery shows that these systems accelerate particles to extremely high energies, and could ...

DC, and colleagues, was titled, "Modulated High-Energy Gamma-Ray Emission from the Microquasar Cygnus X-3." ...

Sources of high-energy cosmic rays in the vicinity of the microquasar V4641 Sag, on the left with energies above a teraelectronvolt, on the right – hundreds of teraelectronvolts. The location of ...

Stellar-mass black holes typically form after a star goes supernova and collapses. However, the discovery of the first-ever triple black hole system, V404 Cygni, complicates that picture. This black ...

V4641 Sagittarii is what's known as a microquasar, and as the name suggests, it kind of functions like a mini version of a regular quasar. The black hole is smaller, the matter source is smaller ...
