Identification of most distant fast radio burst host galaxy

Overview

Astronomers have identified the host galaxy of FRB 20240304B, the most distant fast radio burst (FRB) ever recorded with a known location. The signal, initially detected on March 4, 2024, by the MeerKAT radio telescope in South Africa, traveled for over 10 billion years, originating when the universe was approximately 3 billion years old.

Using the James Webb Space Telescope (JWST), researchers pinpointed the source as a small, young, metal-poor dwarf galaxy characterized by intense star formation. This discovery more than doubles the previous record for a burst with a confirmed host galaxy. The JWST observations measured a redshift of 2.148, confirming the host is a tiny galaxy approximately 1,000 times less massive than those typically associated with such events.

The findings provide critical evidence regarding the origins of FRBs. The characteristics of this host galaxy support the theory that these bursts are produced by young magnetars—highly magnetized neutron stars—rather than the merger of older neutron stars, though the exact cause remains unproven.
