Discovery to unravel mystery of early universe

China Daily  

Scientists have revealed new insights into the distant X-ray universe, with the Einstein Probe satellite offering fresh perspectives on the distant explosions in the cosmos. Follow-up observations from the Gemini-North telescope on Hawaii Island and the Very Large Telescope in Chile returned redshift measurements that confirmed that the burst had come from around 12.5 billion light-years away, beginning its cosmic journey to us when the universe was just 10 percent its current age. These results show that a substantial fraction of FXRTs may be associated with gamma-ray burst, and that sensitive X-ray monitors such as EP can pinpoint them in the distant universe, said Roberto Ricci, a research fellow from University of Rome Tor Vergata in Italy. Combining the power of X-ray and radio observations hands researchers a new way to explore these ancient explosions even without detecting their gamma rays, he said.

Satellite mission finds mysterious celestial object

China Daily  

The wide-field X-ray telescope on the EP satellite detected over 6,800 X-ray sources distributed across the celestial sphere. The EP's advanced Wide-field X-ray Telescope and Follow-up X-ray Telescope enable it to detect X-rays from faint, transient sources that other satellites often miss. Operating 600 kilometers above the Earth's surface, the EP focuses on X-ray sources that could shed light on …

A gamma ray burst — possibly the brightest of all time — sweeps over Earth

Salon  

Earth just got zapped. On Sunday a gamma-ray burst, the most powerful class of explosions in the universe, caused a wave of gamma rays and X-rays to sweep over Earth. In a breathless press release, NASA emphasized that their detectors all over the planet picked up on this, including NASA's Fermi Gamma-ray Space Telescope, the Neil Gehrels Swift Observatory, and …

Indian astronomers part of Nasa team detect radiation from death of a star over 5 billion years ago

India Today  

Part of an astronomy team, Indian astronomers have detected a very short, powerful burst of high-energy radiation that lasted for about a second. While the burst was detected for barely a second, astronomers estimate that it emitted 14 million times the energy released by the entire Milky Way galaxy over the same amount of time, making it one of the …

Artist's rendering of the HXMT telescope. "Since gravitational waves were detected, the study of gamma ray bursts has become more important. The Hard X-ray Modulation Telescope's effective detection area for monitoring gamma ray bursts is 10 times that of the Fermi space telescope. However, Zhang adds, if it cannot detect any gamma ray bursts related to gravitational waves, it may …

Astronomers detect most distant cosmic object-英语点津

China Daily  

Astronomers have discovered evidence of the oldest and most distant cosmic event ever detected, a burst from a dying star that occurred 13 billion years ago, very soon after the birth of the universe. Astronomers say the high-energy gamma-ray burst from the dying star occurred 630 million years after the so-called Big Bang that is believed to have created the …
