The Treble Clef, a radio structure spanning over two million light-years, has been re-examined by Chandra and eROSITA, suggesting it originated from a supermassive black hole and was later energised by a galaxy cluster collision.
01Summary
- 01The Treble Clef (VLSS J0318.9+5755) extends over two million light-years.
- 02Its visible light is hidden by the Milky Way Galaxy.
- 03Recent observations by the Chandra X-ray Observatory and eROSITA support the hypothesis that the central cloud was expelled by a supermassive black hole.
- 04The radio emission may have been reinvigorated by a shock wave from the collision of two galaxy clusters.
- 05The composite image shows radio emission in red and X-rays in blue.
02Why it matters
This unusual radio structure offers unexpected insights into how entire galaxy clusters interact and the broader evolution of the universe, helping astronomers refine models of cosmic structure formation.
