Supernova’s ‘trapped’ jet reveals source of fast X-ray transient
Northwestern UniversityPeer-Reviewed Publication
Fast X-ray transients (FXTs) are blasts of X-rays from distant galaxies. Astronomers have detected FXTs since the 1970s, but their origins have remained unknown. By studying the closest FXT associated with a supernova ever detected, scientists found it was produced by a geyser of high-energy particles trapped inside the outer layer of a massive star.
