Neutron Collapses Killed The Radio Star

A new population of exploding stars must 'switch off' their radio transmissions before collapsing into a Black Hole. But they emit one last strong beam of highly energetic radiation, known as a gamma-ray burst, before they die. It was thought all gamma-ray bursts were followed by a radio afterglow. "But we were wrong. After studying an ultra-sensitive image of gamma-ray bursts with no afterglow, we can now say the theory was incorrect and our telescopes have not failed us," says and Centre for All-sky Astrophysics (CAASTRO) at Curtin University research fellow Dr. Paul Hancock said. read more
