Indian astronomers have recently reported the discovery of 34 new giant radio sources (GRSs) using the Giant Metrewave Radio Telescope (GMRT), operated by National Centre for Radio Astrophysics (NCRA).
- The enormous size and powerful emissions of GRSs offer insights into the large-scale structure of the universe and the distribution and behavior of matter in the cosmos.
About Giant Radio Sources (GRSs):
- GRSs are among the largest objects in the universe.
- They are characterized by massive lobes of radio emissions produced by jets of hot plasma emanating from supermassive black holes at their centers.
- Scientific Value: Studying GRSs helps in understanding the evolution of radio galaxies and the intergalactic medium that contains these massive structures.
Key facts:
- GMRT: It consists of 30 fully steerable gigantic parabolic dishes for research using metre-wavelengths range of radio spectrum.
