Scientists have detected fast radio bursts (FRBs) from an ancient galaxy billions of light-years away, challenging previous theories that linked FRBs only to younger, star-producing galaxies. Notably, a team from Northwestern University observed an FRB emitting 21 pulses over several months from a 'dead' galaxy, which is 11.3 billion years old and contains massive proportions. This discovery opens new avenues for exploration regarding the origins and nature of these cosmic phenomena, suggesting different potential sources beyond current theories.
Researchers from Northwestern University detected an FRB that produced 21 pulses, lasting a few milliseconds, from February through July 2023.
The team's discovery was unique because it was traced back to a 'dead' galaxy no longer producing stars.
It seems to be the most massive FRB host galaxy to date. It's among some of the most massive galaxies out there.
Before this revelation, scientists theorized that FRBs only came from much younger galaxies that are still producing stars.
