Study of Globular Clusters is being carried out in collaboration with ARIES, Nainital by Apara Tripathi, DDUGU. Theoretical studies on chemistry of formation of pre-biotic molecules in interstellar medium are being done by Alka Mishra, LU. Rajesh Kumar, DDUGU studies gravitational collapse and interacting models of dark matter and dark energy. Analysis of Astrosat observations by Sanjay Pandey, LBS Gonda. Continuous monitoring of atmospheric aerosols at Gorakhpur and study of satellite data on atmospheric trace gases are being carried out by Prabhunath Prasad and Shantanu Rastogi, DDUGU. 1.
