Fast radio bursts (or FRBs) are brief yet powerful spurts of radio energy lasting only a few milliseconds. They were first identified in 2007 and their source has remained a mystery. New research shows that the radio emission believed to be an afterglow from FRB 150418 actually originated from a distant galaxy’s core and was unassociated with the FRB.
Catastrophic mergers of binary black holes have been shown to generate gravitational waves, but they can also produce brilliant fireworks of light. Now a team of astronomers has used the Dark Energy Camera (DECam) mounted on the 4-metre Blanco Telescope in Chile in the first detailed search for a visible counterpart of a gravitational wave event.
