The object, named NGC 6099 HLX-1, first appeared in 2009. Chandra caught the bright X-ray flash near the galaxy’s outskirts.

NASA's Hubble and Chandra X-ray Observatories have identified a rare intermediate-mass black hole, NGC 6099 HLX-1, consuming ...

However, a new FRB (dubbed FRB 20240209A), picked up by Northwestern University researchers, is pinpointed to the outskirts of 11.3-billion-year-old galaxy without young, active stars.

The ancient elliptical galaxy where astronomers discovered the radio waves is about 2 billion light-years from Earth and is about 11.3 billion years old, according to the paper.

According to the prevailing “cold dark matter” theory of the evolution of the universe, every galaxy is surrounded by a halo of dark matter that can only be detected indirectly by observing its ...

But, while most FRBs originate well within their galaxies, the team traced FRB 20240209A to the outskirts of its home — 130,000 lightyears from the galaxy’s center where few other stars exist.
