Astronomers detect magnetar heartbeat in gamma-ray burst

universetoday.com

Astronomers detected a magnetar's "heartbeat" within a gamma-ray burst, providing the clearest evidence yet that these powerful explosions can be powered by newborn magnetars. The discovery came from analyzing gamma-ray burst GRB 230307A, which exhibited an unusually long duration. Researchers found a repeating, rhythmic signal indicating the magnetar was spinning 909 times per second. This finding transforms understanding of extreme cosmic events, suggesting newborn magnetars can survive compact star mergers and opening new research avenues in astronomy.
