Astronomers from various countries have discovered the most distant radio galaxy ever known by using data from Giant Metrewave Radio Telescope (GMRT) in Pune.
About:
Giant Metrewave Radio Telescope (GMRT) is located at Khodad, 80 km north of Pune.
It consists of 30 fully- steerable dish type antennas of 45-meter diameter each, spread over a 25-km region.
GMRT is presently the world’s largest radio telescope operating at meter wavelength.
It is operated by the National Centre of Radio Astrophysics (NCRA).
Radio galaxies:
These are type of galaxies that emits more light at radio wavelengths than at visible wavelengths.
They have a supermassive black hole in their centre and emit huge amount of radio waves.
The radio emission is due to the synchrotron process (a process in which electromagnetic radiation is emitted when charged particles are accelerated radially, i.e., when they are subject to an acceleration perpendicular to their velocity).
