Chinese astronomers link repeating fast radio bursts to young supernova remnants using the FAST telescope.
Chinese astronomers using the FAST radio telescope have found strong evidence that some fast radio bursts (FRBs) originate in young supernova remnants.
By monitoring FRB 20190520B for four years, they observed a steady decline in its dispersion measure, indicating the signal travels through a dense, expanding environment.
This suggests the burst comes from a young magnetar in a supernova remnant only 10 to 100 years old, supporting the theory that massive star explosions can produce repeating FRBs.
The discovery, published in Science Bulletin, marks a major advance in understanding FRB origins and highlights FAST’s critical role in long-term radio astronomy.
