GECAM-C provided an accurate measurement of the low energy band spectrum of this GRB, while the Fermi/GBM covered the high energy band where the gamma-ray line showed up. In particular, this burst ...

These brief outpourings of energy are called gamma ray bursts. They are short in duration, lasting from a fraction of a second to a few minutes, and they emit most of their energy as gamma rays.

A team of Chinese researchers has found a giant bubble of ultra-high-energy gamma rays in the Cygnus region of the Milky Way, which reveals the origin of the most energetic cosmic rays ever detected.

Scientists discover low-mass microquasars can accelerate cosmic rays, reshaping theories on high-energy particle origins.

Was a powerful cosmic explosion seen by the Einstein Probe launched by a supermassive black hole snacking on a star, by a ...

On March 15, 2024, a space-based observatory detected bursts of low-energy X-rays from deep in the ancient universe, ...

In the heart of our Milky Way galaxy, two gigantic "bubbles" extend roughly 50,000 light-years above and below the galactic ...

The Einstein Probe is revolutionizing our view of the distant X-ray universe, offering an unprecedented look at some of the ...

Gamma-ray bursts are the most energetic explosions in the universe, releasing as much as a quintillion (10 followed by 18 zeroes) times the energy that is radiated by the sun. This is suspected to ...
