India, June 19 -- The Government of India has issued a release:
Astronomers have traced the mechanism behind a mysterious celestial non-repeating flash of X-ray called Fast X-ray Transients (FXTs) that was detected on November 7 last year. The study of the X-ray flash which they linked to collapse of a massive star or the merger of two neutron stars could help us better understand the physics of these extreme events.
FXTs are energetic, non-repeating flashes of X-rays associated with violent processes in the universe. They are a new class of transient sources in the sky, first discovered about a decade ago. These enigmatic events appear as sudden bursts of low energy X-rays, lasting from a few minutes to several hours, before fading rapid...
