Astronomers Discover Rare ‘Triple-Double’ Radio Galaxy 7.5 Billion Light-Years Away
- Astronomers report the discovery of a rare triple-double radio galaxy located 7.5 billion light-years away.
- The galaxy J022248−060934 shows three pairs of radio lobes from separate activity bursts of its black hole.
- MIGHTEE survey data indicate the black hole’s activity has switched on and off at least three times.
- Outer lobes are at least 16 million years old, formed in the galaxy’s first active phase.
- Second and third active phases lasted about 7 million and 8 million years, respectively.
- The study links the activity cycles to how supermassive black holes influence their host galaxies.
- Future telescopes like the Square Kilometer Array may uncover more TDRGs and broaden understanding.
- The discovery is published in the Monthly Notices of the Royal Astronomical Society.
- Researchers expect more discoveries as radio telescope technology advances.
