Gauribidanur Radio Observatory
Encyclopedia
The Gauribidanur Radio Observatory is a radio telescope observatory located at Gauribidanur
, near Bengaluru. It is operated jointly by Raman Research Institute
and the Indian Institute of Astrophysics
. The observatory has been in operation since 1976.
A few observations with the array have been the first two-dimensional images of radio emission from slowly varying discrete sources in the outer solar corona, an all-sky survey of radio sources at 34.5 MHz in the declination range -30° S to 60° N, and a low frequency carbon recombination lines in astrophysical sources.Studies have been also been done of gaseous remnants of exploding stars and the apparently vacant space between members of a cluster of galaxies. Currently, the studies are targeted at pulsars.
