Fast radio burst

Scientists have found that a radio emission believed to be an afterglow from a mysterious event called fast radio burst, actually originated from a supermassive black hole in the core of a distant galaxy.

What are FRBs?

As their name suggests, fast radio bursts (or FRBs) are brief yet powerful spurts of radio energy lasting only a few milliseconds.

Background:

The first ones were only identified in 2007. Their source has remained a mystery. Most FRBs have been identified in archival data, making immediate follow-up impossible. The new event is only the second one to be identified in real time.
