Astronomers Detect Gamma-Ray Burst’s Magnetic Fingerprint

Astronomers have used the Very Large Array to detect polarized light and Faraday rotation from a gamma-ray burst afterglow for the first time. This discovery allows scientists to map the magnetic fields surrounding these powerful cosmic explosions.
Using NSF’s Very Large Array (VLA), astronomers made the first radio detection of polarized light and Faraday rotation from a gamma-ray burst afterglow, offering an unprecedented glimpse of the magnetic fields surrounding one of the Universe’s most powerful explosions.
