Astronomers detected the brightest fast radio burst ever, RBFLOAT, from a galaxy 130 million light-years away, using advanced telescopes like CHIME and Webb. The findings suggest magnetars as a potential source and provide unprecedented localization, helping to unravel the mystery of these cosmic signals and their origins.
Researchers have linked fast radio bursts (FRBs) to magnetars, highly magnetized neutron stars, which are more frequently found in massive, metal-rich galaxies. This suggests that these galaxies provide the ideal conditions for magnetar formation, often resulting from the merger of massive stars. The study, utilizing the Deep Synoptic Array-110, has localized 70 FRBs, offering insights into the environments conducive to FRB occurrences and magnetar formation.
Astronomers have linked fast radio bursts (FRBs) to massive, star-forming galaxies, suggesting they originate from magnetars—highly magnetic neutron stars formed from stellar mergers. This discovery, led by Kritti Sharma at Caltech, indicates that metal-rich environments in these galaxies may facilitate the formation of magnetars, which are potential sources of FRBs. The study, published in Nature, also explores the possibility that magnetars result from the fusion of two stars, offering insights into their formation and the enigmatic nature of FRBs.

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.
Caltech-led researchers have discovered that fast radio bursts (FRBs) are more likely to occur in massive, metal-rich star-forming galaxies, suggesting that magnetars, which are believed to trigger FRBs, often form from the merger of two stars in such environments. This finding, published in Nature, enhances understanding of magnetar formation and FRB origins, with the Deep Synoptic Array-110 playing a key role in localizing FRBs to their host galaxies.
A new study led by astronomer Kritti Sharma suggests that fast radio bursts (FRBs) are more likely to originate from large galaxies with young star populations, challenging previous assumptions. The research strengthens the theory that magnetars, a type of neutron star, are key progenitors of FRBs, possibly formed through binary star mergers rather than core-collapse supernovae. This finding narrows down the environmental conditions conducive to FRB generation, advancing our understanding of these mysterious cosmic signals.

NASA's NICER and NuSTAR telescopes observed a fast radio burst from the magnetar SGR 1935+2154, providing valuable data on the phenomenon. The burst occurred between two periods of rapid rotational rate increase, followed by a surprising rapid decrease. The increase in high-energy light before the burst led to the telescopes' orientation towards the magnetar. Scientists believe the burst was caused by material eruption from the magnetar's interior, but the exact mechanism behind fast radio bursts remains uncertain. The findings were published in the journal Nature, shedding light on the nature of these mysterious cosmic events.
