Wie Sterne sterben: Astronomen entdecken erstmals den magnetischen Fingerabdruck einer kosmischen Explosion

An international team led by researchers at the University of Arizona and the University of Utah has made a series of landmark observations of one of the universe’s most violent events.

Using the U.S. National Science Foundation Very Large Array radio telescope, operated by the National Radio Astronomy Observatory, the team detected polarized light from a gamma-ray burst afterglow for the first time at radio wavelengths. They also made the first detection of Faraday rotation in a gamma-ray burst – known as a GRB – a phenomenon in which magnetic fields cause the polarization of light to twist as it travels through space.
