Indian radio astronomers have discovered 34 new giant radio sources (GRSs) using data from the TIFR GMRT Sky Survey. GRSs, massive cosmic structures powered by supermassive black holes, challenge previous theories about their formation and environments. This breakthrough, made possible by the Giant Metrewave Radio Telescope (GMRT), provides new insights into the growth and evolution of these structures. The discovery reveals that environmental factors might not solely determine the size of GRSs, suggesting that GRSs represent a critical stage in the evolution of radio galaxies.
5 Major Key Points:
- Discovery of 34 New GRSs: Indian astronomers identified 34 new giant radio sources using data from the TIFR GMRT Sky Survey.
- Role of Supermassive Black Holes: GRSs are powered by supermassive black holes at the centers of galaxies, which create massive jets of plasma and radio emission.
- GMRT’s Crucial Role: The Giant Metrewave Radio Telescope (GMRT) provided essential data for this discovery, covering 90% of the sky at 150 MHz.
- Challenge to Previous Theories: Some newly discovered GRSs, like J0843+0513 and J1138+4540, challenge the belief that GRSs only form in low-density environments.
- Advancement in Understanding: This discovery advances knowledge about GRSs and suggests that their growth may not be solely influenced by environmental factors.
