About Giant Radio Source:
- The Giant Radio Sources are among the largest objects in the Universe.
- These are powered by a supermassive black hole, typically with a mass ranging from ten million to one billion times that of the Sun.
- These super black holes release jets of hot plasma and produce massive lobes of radio emissions, spanning much greater distances than the visible size of the galaxy.
- Astronomers believe that GRSs represent the final stage of radio galaxy evolution due to their enormous sizes.
- Significance
- They help in understanding the evolution of radio sources and studying the intergalactic medium that confines the lobes far from the parent galaxy.
- The study of giant radio galaxies helps scientists comprehend the relationship between black hole activity and the evolution of radio galaxies.
- It also helps scientists understand more about the distribution and behaviour of matter in the cosmos.
