Time-lapse of GRB (VIDEO)

Northwestern University

Caption

In the first-ever time-lapse movie of a short-duration gamma-ray burst in millimeter-wavelength light, we see GRB 21106A as captured with the Atacama Large Millimeter/submillimeter Array (ALMA). The millimeter light seen here pinpoints the location of the event to a distant host galaxy in images captured using the Hubble Space Telescope. The evolution of the millimeter light’s brightness provides information on the energy and geometry of the jets produced in the explosion.
