New Delhi: Indian Scientists have indigenously designed and developed a low-cost optical spectrograph that can locate sources of faint light from distant quasars and galaxies, regions around supermassive black-holes around the galaxies, and cosmic explosions. Named Aries-Devasthal Faint Object Spectrograph & Camera (ADFOSC), the instrument was designed and developed by Aryabhatta Research Institute of observational sciences (ARIES), Nainital, an autonomous institute of the Department of Science and Technology (DST), Government of India. It is about 2.5 times less costly compared to imported ones and can locate sources of light with a photon-rate as low as about 1 photon per second.…
