Astronomers have discovered the first optical afterglow of a short gamma-ray burst, providing evidence for their cosmic explosion hypothesis. The findings suggest that these bursts originate from the merging of compact stars in elliptical galaxies.
The MAGIC telescope has tracked a long duration gamma-ray burst, GRB050713A, in the X-ray and very high energy gamma ray band. The observation was made possible by rapid tracking of the telescope, which allowed it to start observing the source just 20 seconds after an alert from the Swift satellite.
