Hydrogen distribution mapped using Giant metre radiowave telescope (GMRT).

Why in news?

• Astronomers at National Centre of Radio Astrophysics (NCRA), Pune used GMRT to map distribution of atomic hydrogen gas from the galaxy hosting a fast radio burst (FRB) for the first time.
• FRBs are extremely bright radio pulses from distant galaxies that last for only a few milliseconds.

 About Giant Metrewave Radio Telescope (GMRT)

• GMRT is an instrument for studying astrophysical phenomena, ranging from nearby Solar system to the edge of observable Universe, at low radio frequencies (40 to 1450 MHz).
• It is operated by National Centre for Radio Astrophysics (NCRA), which is part of Tata Institute of Fundamental Research.
• It is located near Pune.
