Astronomers trace 84 bright blasts to ancient galaxies

By creating the most extensive catalog to date of high-energy radiation blasts called short gamma-ray bursts (SGRBs), astronomers have traced these mysterious emissions back to active star-forming galaxies in the distant early universe.

Astronomers examined 84 SGRBs — the brightest explosions in the universe — and pinpoint them to their galactic source of origin. They then examined the characteristics of 69 of those galaxies. The team found that 85% of the short gamma-ray bursts they studied originated in young galaxies that are actively forming stars. Additionally, the researchers discovered that the majority of these high-energy radiation bursts were emitted when the 13.8-billion-year-old universe was young.
