New State of Monster black hole detected 5 Billion Light years away

Part of: Mains GS-III: Science and Technology

In News: Indian Astronomers have found an active galaxy in a very bright state with 10 times more X-ray emission than normal, equivalent to more than 10 trillion Sun, and located 5 billion light-years away that could help probe how particles behave under intense gravity and acceleration to the speed of light. 

  • It could help study the role of strong gravity and acceleration of matter in the formation, interaction, and evolution of galaxies in the early universe.
  • Every galaxy in the Universe is believed to host a supermassive black hole (SMBH) at its center. In some galaxies, the black hole is actively devouring a large amount of material and shooting a jet of plasma almost at the speed of light towards us. These are called blazars
  • OJ 287 belongs to a class of blazars known as BL Lacerate objects which show very rapid and large amplitude flux variations but barely discernible emission line features. This class of sources emit in the whole electromagnetic spectrum, a rather uncommon phenomenon which requires extreme physical conditions. 
  • Hence a study of such sources tells us about the behavior of matter in an extreme gravitational field where it is difficult for light also to escape from the vicinity of the black hole.
  • Significant changes in the spectral state of blazars are very rare, and so are the binary SMBH systems in the universe. Multi-wavelength studies of such sources can establish the role of strong gravity and acceleration of particles to the speed of light in the formation of the most energetic jets in the universe, and the formation, interaction, and evolution of galaxies in the early universe.
