Massive Galaxies Emit Mysterious Repeating Radio Bursts
Scientists have discovered that fast radio bursts (FRBs), mysterious and intense energy signals, are more likely to originate from massive, star-forming galaxies rather than low-mass ones. This finding supports the theory that FRBs are linked to magnetars, highly magnetized dead stars, which may form when two stars merge and explode in a supernova. The research, conducted using the Deep Synoptic Array-110, has localized 70 FRBs, providing new insights into their origins and the nature of magnetars. A new array, DSA-2000, is expected to enhance these findings when operational in 2028.
